A heat pump is used to heat water by extracting heat from ambient air. This system is turned to be used to cool a room by extracting heat from the air and reject it to water. The heat pump has a COP of 3.1 (as a heating system). The room receives heat energy from outside at 45, 000 kJ/h. The work done by the compressor is 6.2 kW. The system uses an ideal - vapour compression cycle. a) Draw the schematic of the set-up clearing labelling the components and the relevant energy exchanges. b) What is the rate of heat rejection? Is this enough to meet the cooling requirements and maintain a constant temperature.

A radiator is used to heat an apartment. Water flows through the radiator at a rate of 1 dm³ s1. The temperature at the inlet is 70 °C and 55 °C at the outlet. How much cooling capacity (in W) does this cooler provide? Use the following data: Cp (H2O) = 4.18 J kg-1 K-1, p(H2O) = 997 kg m³.
A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) The temperature of the water bath is monitored, and it is determined from this data that 266. kJ of heat flows out of the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the piston does 220. kJ of work on the system during the reaction.

The molar enthalpy of vaporization of a liquid at its normal boiling point is 39.16 kJ mol-1. When a liquid boils some part of the enthalpy is used in converting the liquid into vapor. The remaining is used in expansion work of the vapor against the external pressure. Calculate what percentage of the enthalpy of vaporization of this liquid is used for the expansion work. Assume that the vapor behaves ideally and that the molar volume of the liquid can be neglected when compared to the molar volume of the vapor. At the normal boiling point of liquid 466.6K, the pressure is 1.00 atm (exactly) by definition.

An open vessel containing liquid water stands in a sealed room measuring 5.0m wide x 4.0m long x 3m high. The temperature of the room is 320K and, over time, some of the liquid water evaporates. Eventually, the liquid water level in the vessel stops changing. a) How many grams of water will be in the humid air within the sealed room? b)A contact lens cleaning system on the market uses an aqueous hydrogen peroxide solution to disinfect the contact lenses. In a few hours, the hydrogen peroxide decomposes to liquid water and oxygen gas in a catalyzed reaction. The vessel in which the reaction occurs has a hole in the top. Use chemical potential to explain how the equilibrium concentration of hydrogen peroxide would be affected if the hole was not present.
An average human produces about 10 MJ of heat each day through metabolic activity. If a human body were an isolated system of mass 65 kg with the heat capacity of water, what temperature rise would the body experience? Human bodies are actually open systems, and the main mechanism of heat loss is through the evaporation of water. What mass of water should be evaporated each day to maintain constant temperature?
