An ideal gas of volume 21 L is enclosed in a cylinder fitted with a piston . At constant temperature and against external pressure of 3 atm , the gas is compressed to one -third of its original volume . Calculate q , w and `Delta U` in the process.

A cylinder fitted with a piston contains an ideal gas with a volume of 21 L. the gas is compressed isothermally to 1/3 rd of its initial volume under a constant external pressure of 3 atm. Calculate q, w and DeltaU .

An 'ideal gas enclosed in a cylinder fitted with a piston of volume ZiL is compressed isothermally to 1//3rd of its initial volume, under the influence of 3 atm constant external pressure. Calculate q. w and Delta U.

Why does the volume of a given mass of gas increase on decreasing its pressure at constant temperature?

The temperature of 1 mol of an ideal monoatomic gas at constant pressure of 1 atm changes from 25^(@)C and 50^(@)C . Calculate Delta U and Delta H in this process, (C_(V)=(3)/(2)R) .

The what temperature must a gas at 300K be colled in order to reduce its volume to 1/3 rd of its original volume, pressure remains constant-

A certain amount of an ideal gas is enclosed in a cylinder fitted with a movable piston. What would be the changes of the volume of the gas in the following processes? (i) The pressure of the gas is reduced by 25% at constant temperature. (ii) The temperature of the gas is increased by 50% constant pressure.

A gas confined in a cylinder with a frictionless piston is made to expand from 1L to 5L under constant pressure of 1.5 atm. During the process, 800J of heat is supplied from external source. Calculate the change in internal energy off the gas. (1L*atm=101.3J) .

To what temperature must a gas at 300K be cooled in order to reduce its volume to (1)/(3)th of its original volume, pressure remaining constant.

The initial volume of a gas is 1 L and the pressure is 16 atm. Due to adiabatic expansion, the final pressure of the gas becomes 2 atm. Find out the final volume of the gas [gamma = 3/2] .
