What component of mechanical refrigeration systems is a device used to increase the pressure of a refrigerant in the gas phase?
A) Receiver
B) Compressor
C) Evaporator
D) Condenser
Answer: B
Explanation: A) Incorrect. A receiver is a tank that stores the liquid phase refrigerant once it leaves the condenser.
B) Correct. A compressor is a device used to increase the pressure of a refrigerant in the gas phase.
C) Incorrect. An evaporator is a heat exchanger that uses the refrigerant to remove heat and, in the process, the refrigerant evaporates.
D) Incorrect. A condenser is a device used to cool the gas phase refrigerant from the compressor so that it condenses back into a liquid phase.

We know five models for activity coefficients: 1-parameter Margules, 2-parameter Margules, Wilson, van Laar and Scatchard-Hildebrand. Identify which of these five models is the best choice to use if the given information is the only information available. For each of the other four models, indicate whether it is (a) not applicable to this problem because necessary information is missing, or (b) applicable, but not the preferred choice. If you say (a), then explain what information is missing, and if you say (b), then explain why you didn’t ch
This problem concerns mixtures of two liquids, W and Z. Some data for pure W and pure Z is given in the table below. No data on mixtures of these compounds is available, but based on their molecular structures, use of the ideal solution model is considered unrealistic. You are going to use a thermodynamic model to predict whether this pair of compounds will form stable liquid mixtures, or whether there will be a miscibility gap, at atmospheric pressure and various temperatures.
