What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
Changes in which no new kinds of matter are produced is called?
A chemical change. Chemical changes can also be indicated if energy is given off. Physical changes on the other hand do not produce energy or produce new substances.
Describe energy in an exothermic reaction?
Light and/or heat energy can both be produced.
How do the properties of substances formed in chemical changes compare to those of the original substances?
two kinds
Why is chemical energy the energy that is converted to thermal energy?
Various kinds of energy may be converted into thermal energy.In a fire it is chemical energy that is converted to thermal energy.However:In a nuclear reactor, nuclear energy is first converted to thermal energy, and eventually to electrical energy.In a fire chemical energy is also converted to light energy.In a battery chemical energy is converted to electrical energy.In braking systems kinetic energy is converted to thermal energy.

What is the four kinds of energy?
Four kinds of energy are:1. Mechanical energy2. Chemical energy3. heat energy4. Light energy
All kinds of energy?
Potential energy, kinetic energy, solar energy, chemical energy, sound energy, nuclear energy, gravitational energy, electric energy, heat energy,
Is the energy that a body in movement possess?
Slinky! No, seriously. A slinky at the top of the stairs has POTENTIAL energy, a slinky falling down the stairs has KINETIC energy. Things with the potential to release energy have POTENTIAL energy. Things currently releasing that energy have KINETIC energy. Of course, it could also be a block of uranium, and it's got energy no matter what it's doing. Or it could be a chunk of wood sitting there, it's got thermal & light energy stored inside it, which would be released by rapid oxidization (burning).
What Kinds of chemical changes?
Exothermic reactions. E.g. combustion, oxidation
What type of chemical absorbs energy?
The two kinds of chemical reactions are endothermic and exothermic. A chemical reaction that absorbs energy is called an endothermic reaction.
Is a change a physical or chemical change?
There are two kinds of changes - physical and chemical. It depends on how the change is made.
What kinds of energy is given off in a chemical reaction?
nuclear
A light bulb changes electrical energy to what other kinds of energy?
Heat and light
Describe energy in an exothermic reaction?
Light and/or heat energy can both be produced.
What are two kinds of energy that travels in waves?
Kinetic and electromagnetic energy can travel in waves.
