It's burning.
endothermic
For example, when ice is melting, the absorbed thermal energy is used to change the phase of the substance - a type of potential energy.
An energy change is where one type of energy EG kinetic is changed to another type of energy by a transducer eg electrical energy. A chemical change is where two substances react to make a new substance
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
Chemical change
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
heat energy
Elastic energy.
chemical change
Thermal energy in a substance is kinetic energy of the molecules that make up the substance.
That is called heat energy.
