A 1.0 kg bar of copper is heated at atmospheric pressure `(1.01xx10^5N//m^2)`. If its temperature increases from `20^@C` to `20^@C`, calculate the change in its internal energy. `alpha=7.0xx10^-6//^@C`, `rho=8.92xx10^3kg//m^3` and `c=387J//kg-^@C`.

The internal energy of a solid also increases when heat is transferred to it from its surroundings. A 5 kg solid bar is heated at atmospheric pressure. Its temperature increases from 20^@C to 70^@C . The linear expansion coefficient of solid bar is 1xx10^(-3)//^(@)C . The density of solid bar is 50 kg//m^3 . The specific heat capacity of solid bar is 200 J//kgC^@ . The atmospheric pressure is 1xx10N//m^2 . The heat transferred to the solid bar is
