During an experiment conducted in a room at 25°C, a laboratory assistant measures that a refrigerator that draws 2 kW of power has removed 30,000 kJ of heat from the refrigerated space, which is maintained at -30°C. The running time of the refrigerator during the experiment was 20 min. Determine if these measurements are reasonable.

One of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?
In a one-shell and two-tube heat exchanger, cold water with inlet temperature of 20°C is heated by hot water supplied at the inlet at 80°C. The cold and hot water flow rates are 5000 kg/h and 10,000 kg/h, respectively. If the shelland- tube heat exchanger has a UAs value of 11,600 W/K, determine the cold water and hot water outlet temperatures. Assume cpc = 4178 J/kg·K and cph = 4188 J/kg·K.
The interior of a refrigerator has a surface area of 6.2 m2 . It is insulated by a 2.9 cm thick material that has a thermal conductivity of 0.0128 J/m · s · ◦ C. The ratio of the heat extracted from the interior to the work done by the motor is 4.6% of the theoretical maximum. The temperature of the room is 10.9 ◦C, and the temperature inside the refrigerator is 0.9 ◦C. Determine the power required to run the compressor. Answer in units of W.
The recommended daily allowance for an average adult that does not want to gain or lose weight is roughly 2000 Calories. Suppose all of that energy was converted into internal energy, with no losses.
