A container of ideal gas has a movable frictionless piston. This container is placed in a very large water bath and slowly compressed so that the temperature of the gas remains constant and equal to the temperature of the water
Which of the following statements about this gas are true for this process? (There may be more than one correct choice.) A) The internal energy of the gas increases during the compression because work is done on the gas. B) Since the gas and water are at the same temperature, no heat can flow between them, which makes this an adiabatic compression. C) The internal (thermal) energy of the gas does not change during the compression. D) Heat leaves the gas during the compression. E) Since the temperature of the gas remains constant, the pressure of the gas must also remain constant.
Springs: A heavy dart and a light dart are launched horizontally on a frictionless table by identical ideal springs. Both springs were initially compressed by the same amount. Which of the following statements about these darts are correct? (There could be more than one correct choice.)
A. The darts both have the same kinetic energy just as they move free of the spring. B. The lighter dart leaves the spring moving faster than the heavy dart. C. The heavy dart had more initial elastic potential energy than the light dart. D. Both darts move free of the spring with the same speed. E. Both darts had the same initial elastic potential energy.
A mandolin is a stringed instrument that consists of 4 pairs of identical strings. Each string in a given pair should be at the same tension as its mate and so should produce the same fundamental frequency. Often such strings may be tuned relative to each other by listening for the beat. As you adjust the tension on one of the strings and you feel the beat frequency, you know that the strings are
closer to being tuned to the same frequency under which of these conditions? 1.The beat frequency gets larger and larger as you adjust the tension. 2.The beat frequency remains constant as you adjust the tension. 3.The beat frequency gets lower and lower as you adjust the tension. 4.It is not possible to tune the strings to the same fundamental frequency by using the beat frequency that exists between them.
