While gas fron a cooking gas cylinder is used, the pressure does not fall appreciably till the last few minutes. Why?

Do you expect the gas in a cooking gas cylinder to obey the ideal gas equation?

Velocity of sound in a gas does not depend on the pressure of the gas. Why?

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically. The ratio of final pressure of gas in B to that of gas in A is

When a gas expands at constant temperature, why does the pressure decrease? Explanin it on the basis of kinetic theory of gases.

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas is container B is compressed to half of its original vlue adiabatically. The ratio of final pressure of gas of B to that of gas in A is

A gas cylinder containing cooking gas can withstand a pressure of 14.9 atm . The pressure gauge of cylinder indicates 12 atm at 27^(@) C . Due to sudden fire in building the temperature starts rising. The temperature at which the cylinder will explode is

A cylinder containing nitrogen gas and some liquid water at a temperature of 25^(@)C . The total pressure in the cylinder is 600 mm. The piston is moved into the cylinder till the volume is halved keeping the temperature constant. If the aqueous tension at 25^(@)C is 23.8 mm, calculate the final total pressure in the cylinder.

At 0^(@) and 760 mm Hg pressure, a gas occupies a volume of 100cm^(3) . The Kelvin temperature of the gas is increased by one fifth, while the pressure is decreased by one fifth times. Calculate the final volume of the gas.

Two cylinders A and B fitted with pistons contain equal amounts of an ideal diatomic gas at 300K. The piston of A is free to move, while that B is held fixed. The same amount of heat is given to the gas in each cylinder. If the rise in temperature of the gas in A is 30K, then the rise in temperature of the gas in B is
