You’re the product safety officer for a company that makes cycling accessories. You’re given a new design for a bicycle pump that includes a cylinder 32 cm long when the pump handle is all the way out. To keep the pump from getting too hot, you specify that the temperature rise should not exceed 75°C when the handle is pushed rapidly, with the outlet blocked, until the internal length of the cylinder is 16 cm. Assuming air initially at 18°C, does the pump meet your temperature-rise criterion?

- Consider a well-insulated horizontal rigid cylinder that is divided into two compartments by a piston that is free to move, but does not allow either gas to leak into the other side. Initially, one side of the piston contains 1 m3 of N2 gas at 500 kPa and 120°C while the other side contains 1 m3 of He gas at 500 kPa and 40°C. Now thermal equilibrium is established in the cylinder as a result of heat transfer through the piston. Using constant specific heats at room temperature, determine the final equilibrium temperature in the cylinder.
