A. 0.825 B. 0.565 C. 0.175 D. 0.950 140) J Such an engine cannot exist. The actual efficiency is higher than the theoretical maximum efficiency, violating the second law of thermodynamics. E. 20°C 2. (10 pts.) Two identical tanks contain the same number of moles of gas at the same pressure and temperature. Tank A contains Oxygen (02, molecular mass = 32 g/mol). Tank B contains Nitrogen (N2, molecular mass = 28 g/mol). In which tank of gas are the particles moving faster? A. Tank A (O2) B. Tank B (N2) C. The velocities of the gases in the two tanks are the same. (10 pts.) A particle follows the trajectory shown below from initial position i to f position f. The potential difference AV is: . 90 V 60 V 30 V 0 V -30 V -60 V 20 V o V 30 V

Explanation / Answer

Correct Answer:

B) Tank B (N2)

Explanation: Parameters like temperature, pressure and volume are same for both the gases, At the same temperature of gases heavier gases travel slower than lighter gases. Nitrogen is lighter than Oxygen, so it travels at a faster average speed.
