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