MIDTERM PREPARATION 2019 Part 1 1. A reversible heat engine has a PV diagram shown in the graph. The net heat transferred between the engine and environment in one cycle is approximately? (A) -0.5 kJ (B) +0.5 kJ (C) -0.6 kJ (D) +0.6 kJ (E) none of the above (A) -0.5 kJ (B) +0.5 kJ (C) -4.2 kJ (D) +4.2 kJ (E) none of the above (A) -0.7 kJ (B) +0.7 kJ (C) -0.6 kJ (D) +0.6 kJ (E) none of the above 2. Given is the two-dimensional gas made out of diatomic molecules. At sufficiently high temperatures the gas molecules are free to move around within the two-dimensional place, as well as to rotate and oscillate. What is the the average energy E avg and the C p of a single molecule of the gas, at [low or intermediate or high]] temperatures [ T < 150 K or 250 K < T < 600 K or T > 3000 K ]? (A) E avg = 1 2 mv 2 x + 1 2 mv 2 y and C p = R (B) E avg = 1 2 mv 2 x + 1 2 mv 2 y + 1 2 Iω 2 and C p = 3 2 R (C) E avg = 1 2 mv 2 x + 1 2 mv 2 y + 1 2 I 1 ω 2 1 + 1 2 I 2 ω 2 2 + 1 2 mv 2 osc + 1 2 kr 2 and C p = 4 R (D) E avg = 1 2 mv 2 x + 1 2 mv 2 y + 1 2 Iω 2 + 1 2 I 2 ω 2 2 + 1 2 mv 2 osc + 1 2 kr 2 and C p = 5 2 R (E) E avg = 1 2 mv 2 x + 1 2 mv 2 y + 1 2 Iω 2 + 1 2 mv 2 osc + 1 2 kr 2 and C p = 7 2 R 3. The figure shows the distribution of the molecular speeds of a gas for two different temperatures T 1 (solid) and T 2 (dashed).
