Alarge block of ice is sitting on a thick copper slab. the bottom surface of the slab is maintained at a temperature of 66.0°c. the upper surface, completely in contact with the ice, is at the temperature of the ice, which is 0°c. the slab is 4.00 cm thick, and has an area of 54.0 cm2. note that copper has a thermal conductivity of 401 w/(mk), aluminum has a thermal conductivity of 237 w/(mk), and the latent heat of fusion of water is 3.35 ✕ 105 j/kg.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
