How are the (i) mass, (ii) volume, and (iii) density of a metallic piece affected, if at all, with increase in temperature?

The parameters are affected in the following ways —

1. Mass — It remains unchanged with an increase in temperature.
2. Volume — It increases with an increase in the temperature.
3. Density — Most of the substances expand on heating and contract on cooling, but their mass remains unchanged. Therefore, the density of most of the substances decreases with the increase in temperature.
