1. A 1 kg block of Al is heated at atmospheric pressure so that its temperature increases from 22.0 degrees C to 40.0 degrees C. (Density of Al= 2.7 g/cm3, Coefficient of linear expansion for Al= 24.0 * 10-6/degrees C, Specific Heat of Al= 900 J/kg degrees C). Calculate:
A) The work done by the Al block
B) The energy added to it by heat
C) The change in its internal energy
