What phrase best describes a exothermic chemical reaction?
A chemical change that gives off heat. Burning paper would be an example.
What two ways is energy involved in a chemical reaction?
When a chemical change occurs, there are two types of ways heat can be involved. In an endothermic reaction, more heat enters the reaction than leaves. In an exothermic reaction, more heat leaves the reaction than enters.
Is heat always released in a chemical reaction?
No. One example of a chemical reaction which releases something other than heat is gamma radiation, which gives off massless light particles (as hard as that is to believe). In addition, all endothermic reactions actually consume heat energy.
What does endithermic change mean?
Endothermic change is a chemical reaction that is accompanied by the absorption of heat, or it is an organism that generates heat to maintain its temperature. When a chemical reaction occurs, energy is transferred to, or from, the surroundings. There is often a temperature change. An example would be that of a bonfire which transfers heat energy to the surroundings.
Means of transport which changes chemical energy into kinetic energy?
Many engines do this conversion. For example, the engines commonly found in cars convert the chemical energy first to heat (by burning it), then convert part of this heat into movement (kinetic energy).
Whar is an example of chemical energy?
heat.
How heat energy transforms into chemical energy?
Burning release heat, for example.
Chemical reaction that produces heat?
Chemical reactions that produce heat (or energy) are known as Exothermic Reactions. (Example: combustion of fuels)
Why is a tree an example of chemical energy?
It stores chemical energy and when you burn wood, that chemical energy is converted to light energy and heat energy.
Give an example of a chemical change that produces light and heat?
you fart on a candle....
What is an example of a chemical reaction that absorbs heat?
dissolving ammonium chloride in water
What is a chemical reaction that happens in home and gives heat?
For example burning of gas.
Example of heat energy?
sun, fire ,and stove are all examples of heat energy!For example heat released during chemical reactions, nuclear fission, nuclear fusion, etc.
The ability of something to conduct heat or sound is an example of one of its properties?
chemical property
How is energy that is stored in chemical bonds used?
For example heat from burning, explosives, etc.
What is indication of a chemical reaction?
HEAT, Heat is the the number one indication of a reaction. Also, changes of state of matter and mass are also indicators of a chemical reaction. an example is when an iron fence rusts.
Why is wood burning an example of chemical energy?
During burning (oxidation) the heat of combustion is released.
