Do energy saving light bulbs have mercury in them?
CFLs do, they could not operate at all without somemercury. However they have much much less than older style fluorescent bulbs/tubes and the manufacturers are improving them so that today's CFL has less mercury than one from a couple years ago and a CFL made in a couple years should have even less.
LEDs don't.
What is the difference between seaweed and algae?
Seaweed is a type of marine algae that is large and multicellular, while algae refers to a diverse group of photosynthetic organisms that can be found in various aquatic environments. In general, seaweed specifically refers to larger, macroscopic algae, while algae can include both macroscopic and microscopic species.
What type of energy is in the match before it is burned and while it is burning?
The energy in a matchstick before it is burned is chemical potential energy stored in the match head. When the match is struck and burned, this chemical potential energy is converted into thermal energy in the form of heat and light.
What country uses natural geothermal energy?
Iceland is a country that extensively uses natural geothermal energy for heating and electricity production due to its abundant geothermal resources. Geothermal energy is harnessed through geothermal power plants and used for various applications such as heating homes, swimming pools, and generating electricity.
What is heat from the earth called?
Geothermal. it is called geothermal. Geothermal thermal energy is what you get when water is pumped through pipes deep under the crust and the water is heated creating steam that travels up the pipe and then is transformed into geothermal heat and energy.
What cellular process uses the most energy?
It depends on the organism and cell type. I will assume you mean the human and all cells in general. In this case generally, it is the production of ATP for use. Yes, creating ATP takes energy, and copious amount of it. The biggest problem is the leakage of H+ ion from the intermembrane space into the matrix, which the H+ pumps must constantly work against. This process creates heat, which is inefficient and also one reason why humans are warm-blooded.
What causes the emission of radiant energy?
Well radiant energy's definition is the movement of photons. So in conclusion i would say kinetic energy cause radiant energy.
What places use geothermal energy?
Geothermal energy is used mainly in countries that lie along tectonic fault lines. Therefore, places such as New Zealand and above all Iceland rely on this form of energy. In fact, I'm sure that Iceland's electricity supply is almost fully based on geothermal energy.
What region of the earth near the equator?
the Equatorial region or zone, it is part of the tropics which is the region between the tropic of capricorn in the south and the tropic of cancer in the north.
The Equatorial zone is the region between 5 degrees north and 5 degrees south.
There is generally 6 zones north to south on the Earth.
1. The arctic bound by the arctic circle, this is the line where, when the north pole is at it's furthest inclination from the sun (winter solstice), the sun does not shine north of here.
2. The northern temperate zone, from the arctic to the tropic.
3. The tropics described above, are the areas on the Earth that at one or two times during the year will directly face the sun.
4. The Equatorial zone described above.
5. The southern temperate zone.
6. And the Antarctic zone, dark during the summer solstice.
A root arising from primary root becomes a secondary root
An electric current is the flow of electric charge through a conductor, such as a wire. This flow is driven by a voltage difference across the conductor and is essential for the operation of electrical devices. The movement of electrons in the conductor creates energy that can be harnessed for various practical applications.
The gas will have thermal energy given by its specific heat capacity (at constant pressure or volume depending on the situation) times the rise in temperature. This thermal energy is possessed because of the increased kinetic energy of its molecules, due to the rise in temperature.
What is the process of burning called?
The process of burning is called combustion. During combustion, a substance reacts with oxygen to produce heat, light, and usually, new substances.
How much oil does the world consume each year?
As of 2021, the world consumes approximately 100 million barrels of oil per day, which totals to around 36.5 billion barrels per year. Oil is a crucial energy source used in transportation, electricity generation, and various industries around the globe.
What raw materials are essential to living things?
an organism uses outside raw materials mostly in the form of food and oxygen . the raw material required by an organisms can be quite varied depending on the complexity of an organisms and its environment
No, clouds are not nonrenewable. Clouds are continuously forming and dissipating as water evaporates from the Earth's surface, rises into the atmosphere, and then condenses into droplets or ice crystals to create clouds. This cyclical process makes clouds a renewable natural phenomenon.
What part do ATP and ADP play in the synthesis of organic molecules?
ATP contains a high energy bond which is used to transfer energy inside cells. This energy is then used to form the bonds that build other organic molecules. Once ATP has been used, it reverts to ADP which lacks the high energy bond of ATP. Cellular respiration releases energy from sugars and fats in order to convert ADP back into ATP.
Is technology widely accepted today in America and other countries?
Is technology widely accepted today in America? We'd probably die without it. Life as we know it would vanish if technology did. To cite just a single example, people would almost certainly wander around like zombies without their cell phones to talk on. In India, yes it is.
What are resources that do not run out called?
Renewable resources. These are natural resources that can be replenished over time, such as sunlight, wind, and water.
Compare the energy storage in photosynthesis to the energy storage in cellular respiration?
Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Cellular respiration is the process in which an organism breaks down fuel to capture energy in a usable form (ATP).
So, the two processes cannot really be compared with respect to energy storage. Photosynthesis is an anabolic process (synthesis of glucose) while respiration is the catabolism of glucose to release the chemical bond energy of the glucose into an usable form (ATP).
How much does it cost for a geothermal system?
The cost of a geothermal system can vary depending on factors such as system size, location, installation method, and additional components. On average, installation costs can range from $10,000 to $30,000 for residential systems, while larger commercial systems can cost significantly more. It's best to consult with a geothermal contractor for a more accurate estimate based on your specific needs.
What are facts about renewable and non renewable energy?
How is electricity made in a way that doesn't harm the environment?
All human activity impacts the environment. The line between impacts and harms is difficult to establish. In the case of electricity generation there are several ways of generating electricity each with its own set of impacts. These are: * Thermal fired generating plants: Systems in which some material coal, gas, biomass is burned can cause thermal pollution of water ways, use water taking it away from other users, have emissions problems (soot, carbon dioxide, nitrogen oxides, sulfur oxides) and have waste disposal issues. Fuel sourcing may entail environmental disruption, processing, transportation and handling issues. The common problem of building the plant and infrastructure exists. * Natural Origin Thermal Power Systems: Steam is recovered from geothermal features (geysers etc.) and used to produce electricity. This is limited to specific geological formations and locations. The common problem of building the plant and infrastructure exists. * Nuclear Thermal Power Systems:Systems in which some radioactive (fissionable) material is used to heat water to steam can cause thermal pollution of water ways, use water taking it away from other users. Fuel sourcing may entail environmental disruption, processing, transportation and handling issues. Waste handling is a significant issue. The common problem of building the plant and infrastructure exists. * Hydroelectric Power Plants: Electricity is created by water pressure or water falling over a cliff. The dams and reservoirs built for these systems disrupt ecosystems over large ares including fish migration as well as being a source of methane (a greenhouse gas) due to anaerobic decomposition. In the case of waterfalls the system diverts or disrupts water flows and fish migration. The common problem of building the plant and infrastructure exists. * Solar Power Systems: Electricity is generated by banks of solar cells. Large installations may require hundreds of acres. The sourcing of materials required for construction of solar panels requires mining and manufacturing issues involving toxic materials. The common problem of building the plant and infrastructure exists. * Wave Power Systems: Electricity is generated by banks of small units powered by the oscillation of waves. Large installations may require hundreds of acres. There is fear that fish, sea mammals and navigation may be impacted by the installations. The common problem of building the plant and infrastructure exists. * Wind Power Systems:Electricity is generated by rows of wind turbines. Large installations may require hundreds of acres. The sourcing of materials required for construction of wind turbines requires mining and manufacturing issues involving toxic materials. There is fear that birds and bats may be impacted by the installations. The common problem of building the plant and infrastructure exists. * Tidal Power Systems: Electricity is created by water pressure or water collected by dikes in tidal estuaries. The dams and reservoirs built for these systems disrupt ecosystems over large areas including fish migration, as well as the diversion or disruption of water flows. The common problem of building the plant and infrastructure exists. * Fuel Cells: Oxidants and fuel are brought together in a catalytic cell to generate electricity. If the fuel is hydrogen the generation of that material requires other polluting sources. If the fuel is methane or other hydrocarbon the cell produces carbon dioxide as well as being produced in some other polluting process. The common problem of building the plant and infrastructure exists. All in all the best source for electricity is probably Natural Origin Thermal Power generation.
