An ideal monoatomic gas is confined in a horizontal cylinder by a spring loaded piston (as shown in the figure). Initially the gas is at temperature , pressure and volume and the spring is in its relaxed state. The gas is then heated very slowly to temperature , pressure and volume . During this process, the piston moves out by a distance . Ignoring the friction between the piston and the cylinder, the correct statement(s) is(are)




Important Questions on Thermodynamics

One mole of a monatomic ideal gas undergoes a cyclic process as shown in the figure (where is the volume and is the temperature). Which of the statements below is (are) true ?


Two rigid boxes containing different ideal gases are placed on a table. The boxes are then put into thermal contact with each other, and heat flows between them until the gases reach a common final temperature (ignore the heat capacity of boxes). Box A contains one mole of nitrogen at temperature , while box contains one mole of helium at temperature . Then the final temperature of the gases, in terms of is

The work of is performed in order to compress one-kilo mole of gas adiabatically and in this process the temperature of the gas increases by The gas is



When a system is taken from state to state along the path, it is found that and . Along the path along the path is
