A gas is confined in a 0.80 m diameter cylinder with a piston, on which rests a weight. The mass of the piston and weight together is 150 kg. The local acceleration of gravity is 9.813 m/s2 and atmospheric pressure is 101.57 kPa.
a) What is the force in nektons exerted on the gas with the atmosphere, the piston, and the weight, assuming no friction between the cylinder and piston?
b) What is the pressure of the gas in kPa?
c) If the gas in the cylinder is heated, it expands, pushing the piston and weight upward. If the piston and weight are raised 0.83 m, what is the work done with the gas in kJ? What is the change in potential energy of the weight and piston?
Moon effect. Some people believe that the Moon controls their activities. If the Moon moves from being directly on the opposite side of Earth from you to being directly overhead, by what percentage does (a) the Moon's gravitational pull on you inc..
