Chapter 7 Question #1 Which of the following state transitions (from 1-2) are consistent with the First Law of Thermodynamics? A. State 1: Two identical blocks of copper are put in contact. One is at 200K the other is at 300K. The two (together) are thermally-insulated from the environment. State 2: Blocks of copper now at T=250K. B. State 1: A flywheel is spinning in air in a thermally-insulated rigid container. The flywheel and air at at the same temperature. State 2: The flywheel has stopped and the air temperature is higher. C. State 1: Gas X fills half of a rigid container and another gas ¥ occupies the other half. The temperature is T. State 2: The gases are uniformly mixed throughout the container and the temperature is T. 1A 2)B 3) 4) All of them 5) None of them 6) | am not sure LO#5 docsity.com
