Microwave ovens have become popular in kitchens everywhere. they are also used in the laboratory, particularly in drying samples for chemical analysis. a typical microwave oven uses radiation with a 12.2 cm wavelength. a.how many moles of photons of this radiation are required to raise the temperature of 345 g of water from 26.5 ºc to 99.8 ºc? b. the watt is a unit of power—the rate at which energy is delivered or consumed: 1 w = 1 j/s. assume that all the energy of a 700. w microwave oven is delivered to the heating of water described in (a). how long will it take to heat the water?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
