Water boils at 120 degree C in a pressure cooker. Explain the reason.
You are inflating the tires on your bicycle using a manual pump. The volume inside of the pump is initially 0.16 m cube with a pressure of 2 atm. If you push down on the piston and reduce the volume inside to 0.07 m cube, what is the new pressure inside of the pump? Assume the temperature inside the pump stays constant.
A meteorological balloon had a radius of 1.75 m when released at sea level at 20°C and expanded to a radius of 3.75 m when it had risen to its maximum altitude where the temperature was -25°C. What is the pressure inside the balloon at that altitude?

- A gas is in a container of volume V0 at pressure P0. It is being pumped out of the container by a piston pump. Each stroke of the piston removes a volume Vs through valve A and then pushes the air out through valve B as shown in Figure P19.74. Derive an expression that relates the pressure Pn of the remaining gas to the number of strokes n that have been applied to the container.

The pump is incapable of lifting the water higher than 10.16 m.
