Answer

The parameters are affected in the following ways —

(i) Mass — It remains unchanged with increase in temperature

(ii) Volume — It increases with an increase in the temperature.

(iii) Density — Most of the substances expand on heating and contract on cooling, but their mass remains unchanged. Therefore, density of most of the substances decreases with the increase in temperature.
