a. What is the essence of the First law of thermodynamics? (A brief clear
statement is sufficient.) b. You are asked to heat a gas from an initial temperature T; to a final temperature Tf. You can add heat at constant pressure or at constant volume. What is more efficient? Explain why. c. What is the essence of the Second law of thermodynamics? (A brief clear
statement is sufficient.) d. Consider one mole of an ideal gas that is allowed to expand from volume V; to volume Vf, (i) What is the change in entropy of the gas and of the external surroundings if the expansion takes place isothermally? (ii) What is the change in entropy of the gas and of the external surroundings if the gas expands freely?
