Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
What happens when fuel such as coal or gasoline burns?
we release the potential energy to heat energy to do work
What are two main forms of energy given off when paper burns?
heat and light and it comes from the reaction of the paper material and its combustion in the air.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
When a piece of wood burns it releases?
When a piece of wood burns, it releases heat energy, water vapor, carbon dioxide, and ash.
What is a substance that can burns in order to produce heat or energy?
coal
What material burns cold?
There is no material that burns cold. Burning is a chemical reaction that releases heat energy.
When substance burn in air what does it produce?
When a substance burns in air, it typically produces carbon dioxide and water vapor, along with any other byproducts specific to the substance being burned. The reaction of the substance with oxygen in the air releases energy in the form of heat and light.
Is combustion one way to release potential energy in a substance?
Yes, combustion is a process that releases potential energy stored in a substance in the form of heat and light. During combustion, a substance reacts with oxygen to produce energy in the form of heat and chemical energy.
Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
What forms of energy is used as a log burns in a fireplace?
Burning or rapid oxidation is a chemical reaction which releases heat.
Does a substance gain energy when it freezes?
When a substance freezes, it releases energy as it changes from a higher-energy state (liquid) to a lower-energy state (solid). The energy is released as heat into the surroundings.
What is the energy output of a fire is called?
The energy output of a fire is called heat. When a fire burns, it releases heat energy into its surrounding environment, which can be felt as warmth or measured in terms of temperature increase.
What energy conversions is a lighted candle?
A lighted candle undergoes chemical energy conversion as the wax burns and releases heat and light energy in the form of a flame.
Explain the type of energy released when fossil fuels are burned?
Basically the same as when any substance burns. Mainly heat energy.
Where does energy come from when a gas stove burns natural gas?
When a gas stove burns natural gas, the energy is derived from the combustion of the natural gas. When the gas combines with oxygen and ignites, it releases heat energy that is used to cook food or heat the surroundings.
