( d Bonus ) For the First Law, show the equivalence between your formulation of question (1b) and the fact that the internal energy is a state function. 2. Some definitions and concepts across the board, part 1 (4 marks) (a) Define “thermodynamic equilibrium”. (b) What if any is the connection between “thermodynamic equilibrium” and “reversible process”? (c)
