A 13cm -diameter cylinder contains argon gas at 10 atm pressure and a temperature of 60?C . A piston can slide in and out of the cylinder. The cylinder's initial length is 23cm . 2500J of heat are transferred to the gas, causing the gas to expand at constant pressure.
What is the final temperature of the cylinder?
What is the final length of the cylinder?
An air puck of mass 0.029 kg is tied to the string and allowed to revolve in a circle of radius 2.0m on a frictionless horizontal surface. The other end of the string passes through a hole in the center of surface, and a mass of 2.6 kg is tied to it...
