Temperature is an intensive physical property.
A change in temperature leads to a change in the kinetic energy of the atoms in the particle.
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Physical Change
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).
Temperature is an intensive physical property.
It is a change of a physical property - for example the variation of temperature.

Decomposition is an entropic change.
During condensation the kinetic energy, or temperature, does not change.
"specific heat"
Concentration.
You think probable to evaporation, a change of phase.
Physical Change
Sound travels faster when the air is warm
