A cylinder with a movable piston contains 3 moles of hydrogen at constant temperature and pressrue. The walls of a cylinder are made up of a heat insulator and the piston is insulated by having a pile of sand on it By what factor does the pressure of a gas increases if the gas is compressed to half its original volume ?

At what temperature the mean speed of the molecules of hydrogen gas equals the escape speed from the earth?

Figure shows two vessels with adiabatic walls, one containing 0.1 g of helium (gamma =1.67 , M = 4 g mol^(-1)) and the other containing some amount of hydrogen (gamma = 1.4, M = 2 g mol^(-1)) . Initially , the temperatures of the two gases are equal. The gases electrically heated for some time during which equal amounts of heat are given to the gases. It is found that the temperatures rise through the same amount in the two vessels. Calculate the mass of hydrogen.
