Energy

You could say so. About half the total oil imported to the US is used for transport-is your journey necessary? Travelling for business ought to be reducing, with modern internet facilities being used instead. But we see everywhere conferences being called on a global scale, and mass tourism being encouraged.

Oil is also essential for plastics, but I'm old enough to remember the world before plastics, we used paper bags, and clothes made from natural materials. Well if and when the oil runs out we shall have to find alternatives, but may not be able to maintain our present way of life which does rely on oil so heavily.

The energy stored in the center of atoms is nuclear energy. This energy is released through processes like nuclear fission and fusion, where the nucleus of an atom is split or combined, leading to the release of immense amounts of energy.

A light bulb: Electrical energy passes through a tungsten filament, heating it up to between 2527 ºC (2800 K) and 3027 ºC (3300 K), which causes the filament to glow brightly, converting the thermal energy to light energy.

Vision is the process where the eye responds to electromagnetic radiation in the visible part of the spectrum, that is a range of frequencies. So that is electromagnetic energy. The eye itself is driven by a whole range of bodily processes which are essentially using chemical energy.

A flashlight gives off light energy, which is a form of electromagnetic radiation. The light energy is created when the flashlight's batteries produce electrical energy that powers the light bulb or LED to emit light.

Lipids, such as fats and oils, are macromolecules that store energy efficiently in living organisms. They contain long hydrocarbon chains that can be broken down through metabolic processes to release energy for cellular activities.

Natural gas is found deep below the earth's surface. Much of it is contained in shale rock. A modern technology called fracking (hydraulic fracturing), which uses high water pressure to break up the shale rock is used to recover natural gas. The natural gas is then refined and used. The United States has an abundance of natural gas that can be recovered. Natural gas is currently used to heat our homes and run home appliances. It has recently been used to power transit buses and trucks. Natural gas buses are becoming very prevalent. Natural gas vehicles are becoming much more common as natural gas is the cleanest burning fuel in existence today.

The large object moving at 25 mph would have more kinetic energy compared to the small object, assuming they have the same mass. Kinetic energy is dependent on both mass and velocity, so in this case, the larger object would have more kinetic energy due to its greater mass.

It has been said humans can live on any sort of food. By definition food must mean something that provides energy, if not then it is not food.

The name of the energy that holds atoms together in a molecule is called chemical bonds.

If a glass ball on a lightning rod is struck by lightning, it may shatter due to the extreme heat generated by the lightning strike. Additionally, the lightning may travel through the rod to the ground, protecting the building from damage.

Solar energy is transported through food chains/webs in ecosystems, as part of an energy pyramid, which has 3 main trophic levels: * Level 1: Autotrophs (plants) fix the energy from the sun during photosynthesis; the energy becomes part of the plant biomass * Level 2: Herbivores consume the plants * Level 3: Primary carnivores feed on herbivores, and are consumed by: * ** Secondary carnivores At each level the energy consumed is assimilated and then either respired, or becomes part of the biomass. Some species participate at more than one trophic level, for instance birds which are herbivores and carnivores. Ecosystems are not very efficient at capturing solar energy; plants capture only 1% of the energy available from sunlight, and far less than that eventually reaches the top of the pyramid.

The world's biggest suntrap is located in Seville, Spain. This structure, known as the PS10 Solar Power Plant, is a solar power station that uses concentrated solar power to generate electricity.

Geothermal energy can only be exploited where the geology causes the right conditions, a source of heat near the earth's surface that is stable and allows a power plant to be built. An active volcano wouldn't be any use as the plant would probably be wrecked after a short time. Once the electricity is generated it can be sent to the nearest substation.

The energy source that starts a firework is most commonly a fuse, which is a cord that contains a combustible material. When the fuse is ignited, it burns slowly until it reaches the explosive components of the firework, causing it to ignite and produce colorful effects.

The term for organic matter that contains stored energy is biomass. Biomass can be used as a source of renewable energy through processes such as combustion or fermentation.

You can heat up water into steam which then rises and this turns turbines, which turn the movement into electricity. Power plants use this method to generate electricity: They burn coal to heat water to turn turbines to generate electricity.

The complete process is chemical > heat > kinetic > electrical.

When the average energy of a liquid's particles decreases, the temperature of the liquid will lower. This may lead to a phase change, such as the liquid turning into a solid if the energy decreases enough. Additionally, the movement of the particles within the liquid will slow down as the temperature drops.

To calculate the cost, you need to first convert the wattage to kilowatts by dividing 25 watts by 1000 (since 1 kilowatt = 1000 watts), which equals 0.025 kW. Next, multiply the kilowatts (0.025 kW) by the number of hours the light bulb is on (24 hours) to get 0.6 kWh. Finally, multiply this by the cost per kWh ($0.085156) to get the total cost, which is approximately $0.0511.

The primary way the Sun's energy reaches Earth is through electromagnetic radiation, particularly in the form of visible light. This light energy is absorbed by the Earth's surface and then converted into other forms of energy, such as heat and chemical energy through processes like photosynthesis.

When ever there is a change, no matter how small, this involves energy.

Energy is involved everywhere around us, we just do not see it or count on it being some form of energy.

Even dust floating in the air transforms and uses energy.

Exhaustible resources are finite and can be depleted over time, such as fossil fuels. Inexhaustible resources are essentially unlimited and can be continuously replenished, such as solar or wind energy.

A car would have the most potential energy when it is at its highest point or at the top of a hill. This is because potential energy is height-dependent, and the higher an object is above the ground, the greater its potential energy due to gravity.

The process of burning wood in an insufficient supply of air or oxygen is called incomplete combustion. This leads to the generation of carbon monoxide instead of carbon dioxide, which can be harmful if inhaled.
