Question

Consider 200 g of metal A and 50 g of metal B at different temperatures. They are brought together and reach thermal equilibrium in an irreversible process without exchanging any heat with the environment. During this process, does the total entropy of two metals together increase, decrease, or remain the same, or is not determinable with the given information. Explain your answer. Which system (or systems) has the largest average translational kinetic energy per molecule? 2 mol of He at p = 2 atm, T = 300 K 1 mol of N_2 at p = 0.5 atm, T = 600 K 1 mol of He at p = 1 atm, T = 300 K 2 mol of N_2 at p = 0.5 atm, T = 450 K 1 mol of Ar at p = 0.5 atm, T = 450 K 2 mol of Ar at p = 2 atm, T = 300 K If two objects are in thermal equilibrium with each other they cannot be moving. they cannot be ax different temperatures. they cannot be undergoing an elastic collision. they cannot have different pressures. they cannot be failing in the Earth's gravitational field.
