Yes it is a physical change.

Thermal conductivity is a physical property.
This is a chemical change (thermal decomposition).
Heating is a physical process but thermal decomposition is a chemical process.
It is a physical property. As there is no change in chemical composition and only size increases.
Thermal expansion will occur in just about all of the 15 or more phases of matter: whether it be solid, liquid, gas, etc.
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
Expansion (either of a solid or steam) and evaporation are two of these physical changes.
when your feet go in shoes and then your feet expand and contract so your shoes will not fit.
Thermal growth is more commonly known as thermal expansion. It is the tendency of matter to change in volume in response to a change in temperature.
The cause is the thermal expansion of materials.
Physical.
Thermal expansion is used in thermostats, or heat-regulating devices.
thermal expansion
Increase or decrease of demand due to change in price
No. "Chemical change" means that the bonds between atoms are rearranged.
