You get to the dive site, put on your gear, and are ready to go under. You check your scuba tank. It is filled to a pressure of about 22,000 kPa (kilopascals) at a temperature of 300 K. The volume of the tank is 25 L. You begin to wonder: If temperature remains constant, what would happen to the volume of gas in the tank if its pressure increased?

A. List and briefly describe the four thermal processes where pressure, volume, temperature, and heat are each held constant.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
