1.	apply the first law of thermodynamics to determine the change in internal energy during boiling and melting process
Answer» Therefore, DW= P (DV) = P x 0 = 0. So, the internal energy during the MELTING process increases by (ML) at constant temperature. This is due to increase in internal potential energy (UP). The internal kinetic energy ( UK ) REMAINS constant. ... Adiabatic Process. dQ = dU + dW = 0 or dU = – dW

Answer»

Therefore, DW= P (DV) = P x 0 = 0. So, the internal energy during the MELTING process increases by (ML) at constant temperature. This is due to increase in internal potential energy (UP). The internal kinetic energy ( UK ) REMAINS constant.

Adiabatic Process.

dQ = dU + dW = 0

or dU = – dW
