The change in the internal energy of a substance

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
