It can be either.
A hot cup of water, which just sits and becomes cooler, is releasing heat energy and if it is outside in really cold weather it will freeze. This is just a physical change.
Burning oil, paper, wood, coal, any substance like those, releases heat energy also, but these are all chemical changes.
What else can I help you with?
Is a burning match a example of physical energy into chemical energy?
Yes, a burning match is an example of chemical energy being released through a chemical reaction. When the match is ignited, the chemical bonds in the matchstick are broken down, releasing stored energy in the form of heat and light.
Chemical change releasing energy in cells?

Does freezing water have physical energy or chemical?
physical energy
Is fizzing is an example of physical change?
Fizzing is the result of a chemical change - a chemical reaction with gas releasing.
Is a cell breaking down food and releasing energy a physical change?
Its not a physical change because, the food broken down can't go back to its original form. All in all, its a chemical change.
What type of energy is wood?
It is the breaking of chemical bonds, and therefore is releasing chemical energy.
What type of energy is a burning campfire?
