A copper block of mass 5 kg, initially at equilibrium with the surroundings at 30oC and 100

Question:

A copper block of mass 5 kg, initially at equilibrium with the surroundings at 30oC and 100 kPa, is placed in a pressurized chamber with a pressure of 20 MPa and a temperature of 200oC. Determine
(a) The change in the internal energy (ΔU).
(b) Enthalpy (ΔH)
(c) Entropy (ΔS) of the block after it comes to a new equilibrium.
(d) What-if Scenario: What would the change in internal energy be if the block were made of silver?
