Problem 4 – 8 points a cube of wood with mass m = 1.0 kg floats 80% submerged in a cylinder filled with water (water density = 1000 kg/m3). the cylinder is open to the atmosphere at the top. use g = 10 m/s2 and take atmospheric pressure to be 100 kpa.
(a) calculate the density of the wood.
(b) calculate the minimum mass of a metal cube which, when placed on top of the wood cube, will make the wood cube float 100% submerged.

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
