The Helmholtz free energy of a liquid column that rises, due to surface tension, inside a capillary tube (Figure 1), as a function of the height, h, is given by: F(h) =(ro)gr^2h^2/2 = -2 pi sigma r h cos teta, where r is the radius of the tube, g is the local ac- celaration of gravity, is the surface tension of the liquid, and is the contact angle of the liquid in contact with the wall of the tube.

Air in a cylinder-piston system expands and works on the piston. The temperature of the air decreases during the process from the initial temperature of (30×1.6)°C down to the final temperature of 20°C. Specific heat values of air at constant pressure and constant volume are 1,000 J/kg.K and 730 J/kg.K respectively. (a) Determine the change of enthalpy per mass and the change of internal energy per mass, respectively. (b) This process produces 20 kJ/kg of work. Combine this number with your outcome from (a), to estimate the amount of heat transfer per mass required for this process to happen.c) Based on the outcome from part (b), determine whether the heat went ‘into’ the system or ‘out of’ the system.
