A solid object has a volume density o at atemper... A solid object has a volume

Question

A solid object has a volume density o at atemper... A solid object has a volume density o at atemperature of 315K. The coefficient of the volume expansionfor the material for which its made is 7.00 x10-5K-1. What will the density be (interms of o) at a temperature of 425K, assumingthat it does not melt and that its thermal properties do not changewith temperature.

Explanation / Answer

As we know that the relation of the coefficient of linear expansion is given by

V=VoT

and relation between mass, volume and density is given by

= m/V

Given that it does not metl, it means its volume remains same and thermal properties means volume expansion remain same in both the cases.

density change when mass and volume change but if it does not melt then density remain same because volume and mass are same in both the cases.
