2. a thermodynamic process that maintains a constant volume is called an isochoric process. during these types of processes, the gas does no work because it is not increasing the volume of the container. if you sealed off the top of a water bottle and shook 100 ml of water for two minutes, you would find that the water is warmer when you take a drink. if you shook the water long enough to raise the water’s temperature 5 ºc, what is the change in internal energy of the system

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
