A piston-cylinder assembly contains a gas at a pressure of 100 kPa. The mass of the piston (mpiston) is 8 kg and its diameter is 12 cm. a) Calculate the atmospheric pressure. b) The pressure of the gas in the cylinder is increased by placing weight on the piston. Calculate the mass of the weight to be put so that the pressure of the gas in the cylinder can be twice the initial pressure. (Gravitational acceleration 9,81 m / s2)
