How is energy released from fossil fuels?

Fossil fuels must be burned to release their energy.

What converts chemical energy stored in food into a form that can be easily used by the cell?

The process of cellular respiration converts chemical energy stored in food molecules (such as glucose) into a form of energy called adenosine triphosphate (ATP), which can be readily used by the cell for various functions and activities. This process involves a series of biochemical reactions that occur in the mitochondria of the cell.

What is an example of atp synthase?

ATP synthase is a protein complex found in the inner membrane of mitochondria and the thylakoid membrane of chloroplasts. It helps generate ATP by using a proton gradient established across the membrane to drive the synthesis of ATP from ADP and inorganic phosphate.

Where is the energy source found that drives the process that form igneous and metamorphic rock?

The energy source that drives the formation of igneous and metamorphic rocks is primarily heat generated by Earth's internal processes, such as volcanic activity or tectonic movements. This heat can come from the Earth's mantle or from the radioactive decay of elements within the crust. It causes rocks to melt and recrystallize, forming new rocks through processes like solidification or metamorphism.

What is a example for chemical energy?

Chemical potential examples are like, Icy Hot ( the pain patch or cream ) or a Light Stick ( the ones you break/crack and the glow ) hope this helps a little :)

Is chemical energy stored in chemical bonds?

Energy is released when a chemical bond is created between two atoms.

Energy is stored when the bond is broken.

CHEMICAL ENERGY IS ENERGY STORED IN BONDS IN A BODY OR SYSTEM AND IS RELEASED DURING A CHEMICAL REACTION EG. IN A CAR BATTERY, FOOD, FUEL
No, chemical potential energy is not stored in chemical bonds. Chemical potential energy is the potential to form bonds. It lies in the absence of bonds. Sometimes it is necessary to break an existing bond before forming a new bond, but breaking the existing bond consumes energy. Forming the new bond releases energy.

What the volume and shape of solid?

To determine the volume of a solid, you would need to know the appropriate formula based on the shape. Common formulas include volume = length × width × height for a rectangular solid, volume = πr^2h for a cylinder, and volume = (4/3)πr^3 for a sphere. The shape of the solid would determine which formula to use for calculating its volume.

How do you get pressure of 100 millibar from propane gas bottle?

To achieve a pressure of 100 millibar from a propane gas bottle, you would regulate the flow using a pressure regulator. Make sure the regulator is compatible with propane gas and set it to the desired pressure. Attach the regulator to the propane gas bottle, open the valve slowly, and adjust the regulator until the pressure gauge reads 100 millibar.

What characteristic do fossil fuels soil and sunlight all share?

All three are natural resources that can be depleted if not managed sustainably. They are also crucial for various human activities such as energy production, agriculture, and photosynthesis.

Energy and earths resources?

Earth's resources are finite, and the way we extract and use energy from them can have negative impacts on the environment. It is important to shift towards renewable energy sources and sustainable practices to reduce our reliance on non-renewable resources and minimize harm to the planet. By promoting energy efficiency and conservation, we can help preserve Earth's resources for future generations.

How much of solar energy that falls on the leaves of a plant is converted to chemical energy by photosynthesis?

On average, plants are able to convert about 1-2% of the solar energy that falls on their leaves into chemical energy through photosynthesis. The efficiency can vary depending on factors such as the type of plant, environmental conditions, and available resources.

What polymer acts as an energy storage molecule?

Polymer glycogen acts as an energy storage molecule in animals, while polymer starch fulfills this function in plants. Both polymers consist of glucose monomers linked together in a chain-like structure, allowing for quick breakdown and release of energy when needed.

What chemical process provides a plant with energy to carry on all other living activities?

The process of photosynthesis provides plants with energy to carry out all other living activities. During photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose (sugar) and oxygen. This process allows plants to produce their own food and energy.

Does fermentation or respiration release more energy for an athlete's muscles?

Respiration releases more energy for an athlete's muscles compared to fermentation. Respiration is a more efficient process that produces more ATP (energy currency of the cell) per molecule of glucose than fermentation. This allows athletes to sustain high-intensity activities for longer periods of time.

Is using oven cleaner a physical or chemical change?

Traditional oven cleaner is lye, it chemically turns the baked on fat and oil to soap. This soap then helps clean off the other baked on stuff.

I don't know (yet) how the new lye free oven cleaners work.

What is release when fuels burn?

depends on the fuel. when a fuel burns, its components react with oxygen, so you get lots of oxides. for example, when you burn a mole of natural gas, (CH4) the carbon forms two double bonds with oxygen to make 1 mole CO2, while the four hydrogens react with two oxygens to make 2 moles H2O. Hope this helps!

What is the process called that converts light energy from the sun into chemical energy in the form of organic compounds primarily carbohydrates?

This process is called photosynthesis. It occurs in plants, algae, and some bacteria, where light energy is used to convert carbon dioxide and water into glucose (a form of sugar) and oxygen. This conversion is essential for sustaining life on Earth as it provides the energy source for most living organisms.

What is the standard electrode potential of carbon?

The standard electrode potential of carbon is 0 V when referenced against the standard hydrogen electrode (SHE). This means that carbon is neither a strong oxidizing agent nor a strong reducing agent under standard conditions.

What is the energy released when steam condenses to water?

The energy released when steam condenses to water is called the latent heat of vaporization. This energy is released in the form of heat as the steam loses its thermal energy and transitions back into liquid water.

Why shouldn't you put a pressurised deodorant can near a hot fire?

Pressurized deodorant cans can explode when exposed to high temperatures such as a hot fire. The heat can cause the pressure inside the can to increase rapidly, leading to the container bursting and potentially causing harm and injury. It is best to keep pressurized cans away from heat sources to prevent accidents.

What is potential energy stored in the bonds of molecules called?

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

Which organelle carries out photosynthesis converting light into chemical energy?

Chloroplasts are the organelles that carry out photosynthesis in plant cells, converting light energy into chemical energy in the form of glucose. They contain chlorophyll, a pigment that absorbs light and initiates the process of photosynthesis.

What determines whether energy will be released or absorbed during a chemical reaction?

The difference in energy between the products and reactants of a chemical reaction determines if energy will be released or absorbed. If the products have lower energy than the reactants, energy will be released in the form of heat or light. If the products have higher energy, then energy will be absorbed.

Is it true that if an chemical reactions that absorb energy will not occur without a source of energy?

Yes, for chemical reactions that require an input of energy (endothermic reactions), they will not proceed without an external source of energy. This energy is needed to break the existing bonds in the reactants before new bonds can form in the products.

What is a chemical reaction in green plants that produces energy and oxygen?

Photosynthesis is the chemical reaction in green plants that produces energy in the form of glucose and releases oxygen as a byproduct. This process involves the absorption of sunlight, water, and carbon dioxide, which are converted into glucose and oxygen with the help of chlorophyll in the chloroplasts of plant cells.
