(A) True
(B)False

1, The first law of thermodynamics states that energy ________be generated or destroyed in an isolated system. (A) "can" (B) "cannot"

2, The second law of thermodynamics indicates that the total entropy of an isolated system must________ when undergoing an irreversible process. (A) "increase" (B) "decrease" (C) "stay the same"

3, According to the third law of thermodynamics, the entropy of a system reaches a minimum at the________. (A) "absolute zero" (B) "melting temperature" (C) "below freezing temperature"

4, Collisions between ideal gas molecules are completely elastic. (A) True (B) False

6, A material's specific heat capacity describes the amount of heat required to raise the temperature of 1.0 mole of material by 1.0 degree Celsius. (A) True (B)False

7, A process with a negative change in Gibbs free energy is thermodynamically favorable. (A) True (B) False

8, An ideal gas has a higher specific heat at constant pressure (Cp) than its specific heat at constant volume (Cv). This is because______? (A) Gas expanding at constant pressure does work on the environment when its temperature is increased. (B) Gas's internal energy increases more when held at constant pressure than when held at constant volume. (C) Pressure of the gas remains constant if the temperature is held constant. (D)More heat is required to heat up gas at increasing pressure than at increasing volumes.

9, A 2D system consisting of 16 black and white components arranged in various configurations in a 4 by 4 grid. Among the following 3 configurations below, which one has the highest entropy? (A)(B)(C)

10, A system undergoing a perfectly reversible thermodynamic process must have the following characteristic? (A) The internal energy of the system needs to be constant throughout the process. (B) Entropy of the system and its surrounding does not change. (C) The work done by the system must be equal to the work done to the system. (D)Temperature of the system must stay constant throughout the process.

11, Sam, a typical college student, needs to bake a mini cubical cake of 512.0 cm3for an upcoming party. The cake dough needs to be heated from 25℃ to 190℃ and baked for 1.5 hours. However, the kitchen oven is broken, and the only heat source available is a large old electric stove that heats up to 120℃. If Sam puts the cake onto the 120℃ electric stove, is it possible to concentrate the heat from electric stove and heat the cake to 190 ℃? (A) Yes, it is possible if the stove is at least 3 times as large as the cake. (B) Yes, if the cake dough is placed at the exact center of the stove, heat would flow in from all sides to heat it up. (C) No, heat cannot flow from a colder object to a hotter object. (D)No, because heating the cake dough like this would violate the first law of thermodynamnics.
