NAME 4) (3 points) The first law of thermodynamics states that although energy assumes many forms, the total quantity of energy in a specific system is constant. TRUE FALSE 5) (3 points) Heat and work exist only as energy in transit from one body to another. TRUE FALSE 6) (3 points) The compressibility factor for an ideal gas is always 1, regardless of its thermodynamic state such as temperature or pressure. TRUE FALSE 7) (3 points) All fluids at the same reduced temperature and reduced pressure have approximately the same compressibility factor TRUE FALSE 8) (3 points) Dr. Smith is my favorite Chemical Engineering Professor. TRUE FALSE 9) (3 points) The second law of thermodynamics puts restrictions on energy transformation from heat to work. In other words, it says that heat cannot be converted into work. 10) (3 points) Sensible heat effects are characterized by temperature changes. 11)(3 points) The Triple point is identified in Figure 3.1 from the text. Identify the Triple point in Figure TRUE FALSE TRUE FALSE 3.2a by circling it. 12) (3 points) Draw an isotherm on Figure 3.1 that is similar to "T" on Figure 3.2b. 13) (6 points) If the vapor pressure of acetone at 60°C is 115 kPa, calculate the reduced temperature and reduced pressure kJ of work for each kJ of heat extracted from a hot reservoir at 255'C with heat rejected at 30'C. How much of the $3,500,000 capital budget do you recommend the company invest this year? 14) (20 points) An entrepreneur wants your company to invest $1,000,000 in her process that produces 0.sExplanation / Answer
4)True. The frist law of thermodynamics or law of conservation of energy states that the total energy of an isolated system is constant. energy can be transformed from one form to another, but can be neither created nor destroyed.
5)True. A body always contains internal energy.But ,
during interaction there is transfers of heat energy, or their is a work transfer.
6)True. Compresiblty factor is a measure of how much the thermodynamic properties of a real gas deviate from those expected of an ideal gas.For ideal gas its value is 1.
7)True According to theorum of corresponding states
All fluids when compared at the same reduced temperature and reduced pressure,have approximately the same
compressibility factor, and all deviate from ideal gas behavior to about the same degree
