The sidewalk being warmed by the heat of the sun is a physical change not a chemical change.
Phicicl
It undergoes a physical change because the matter that makes up the sidewalk does not change. THe side walk goes through a chemical and physical change because the heat makes it constrict by shacking the particles just like it happens with food
Producing heat is caused by a chemical process which results in physical changes. The cause is chemical. The effect is physical. :) :D

Thermal conductivity is a physical property.
Heat brings about a chemical change. Physical changes can be undone, but you cannot unbake a cake.

Heat of fusion is a physical property.
Chemical
Chemical, there is an interaction between the different chemicals in the heat pack.
Heat is a physical stressor.
Heat capacity is a physical property.

Physical
The ability to conduct heat does not involve a chemical reaction, so it can't be a chemical property. Therefore, it is a physical property.
as far as i know its a physical property
i think it would be physical because it is still energy.
