Document Summary
Phy1122 a discussion group february 11, 12 2015. A freezer converts 0. 5 kg of water at 10 c to ice at 8 c. The specific heat of water and ice is, respectively, 4184 and 2050 j/(kg k), and the heat of fusion of water is 334 103 j/kg. An ideal monatomic gas expands isothermally from state a to state b. Answer: c: what is the ratio of internal energy of the gas in state c to that in state a, 2/1, 1/2, 240/600, 600/240, 130/327. E) how much work is done on the gas as it is compressed isobarically from state. C to state d: zero, 200 j, 400 j, 600 j, 800 j, what is the net amount of work done after complete cycle, zero, 20 j, 40 j, 1000 j, 1340 j. An ideal gas with cp/cv = 1. 40 is carried through the cycle illustrated here.
