Air in a cylinder is suddenly compressed by a piston, which is then maintained at the same position. With the passage of time

A gas is contained in a metallic cylinder fitted with a piston.the piston is suddenly moved in to compress the gas and is maintained at this position. As time passes the pressure of the gas in the cylinder

There is a soap bubble of radius 2.4 xx 10^(-4)m in air cylinder at a pressure of 10^(5) N//m^(2) . The air in the cylinder is compressed isothermal untill the radius of the bubble is halved. Calculate teh new pressure of air in the cylinder. Surface tension of soap solution is 0.08 Nm^(-1) .

There is a soap bubble of radius 2.4xx10^(-4)m in air cylinder which is originally at a pressure of 10^(5)(N)/(m^(2)) . The air in the cylinder is now compressed isothermally untill the radius of the bubble is halved. (the surface tension of the soap film is 0.08Nm^(-1)) . The pressure of air in the cylinder is found to be 8.08xx10^(n)(N)/(m^(2)) . What is the value of n?

A gas is enclosed in a cylindrical can fitted with a piston. The walls of the can and the piston are adiabatic. The initial pressure , volume and temperture of the gas are 100 kpa, 400cm^(3) and 300k respectively. The ratio of the specific heat capacities of the gas is (C_p / C_v = 1.5) Find the pressure and the temperature of the gas if it is (a) suddenly compressed (b) slowly compressed to 100 cm^(3).

A gas for which gamma=1.5 is suddenly compressed to 1//4 th of the initial volume. Then the ratio of the final to initial pressure is

An ideal gas is enclosed in a cylinder having cross sectional area A. The piston of mass M has its lower face inclined at theta to the horizontal. The lower face of the piston also has a hemispherical bulge of radius r. The atmospheric pressure is P_(0) . (a) Find pressure of the gas. (b) The piston is slowly pulled up by a distance x. During the process the piston is always maintained in equilibrium by adding heat to the gas. [It means if the piston is left at any stage it will stay there in equilibrium]. Find change in temperature of the gas. Number of mole of the gas in the cylinder is one.
