3. Determine the amount of work done, the heat of the process, the change in internal energy, enthalpy, Gibbs energy and entropy of 2.00 moles of oxygen (Ср=29.37 J mol-1 K-1 S0 298=20.5 J mol-1 K- 1.
1) isothermally compressed to a volume equal to half of the original;
2) isochorically heated to Т2=525.0 С
All processes were carried out reversibly. Give the derivation of the necessary calculation expressions based on the expression of the first law of thermodynamics for the definitions of heat, work and heat capacity.
