Unformatted text preview: . (a) What is V 1 ? (b) Changing to p 2 = 170kPa, what is the work and V 2 ? (c) Redo (a, b) for one mol of ideal gas at 300 K. The gas constant is R = 8 . 31J/(mol K). 4. (3 points) Why can you not cool your kitchen by opening the refrigerator door? Why does it work with an air conditioner? 5. (4 points, This problem was on Midterm 1, 2008) We have a closed system containing an ideal gas ( pV = aT, c v = b ; a,b constants). (a) Calculate the work to triple the pressure from p to 3 p . What is the sign? (b) How much heat is transferred (and which way) in part (a) if T is constant. (c) Now we perform the compression of part (a) under constant internal energy, how does the temperature change?...
