	How much work to be done in decreasing the volume of and ideal gas by an amount of $2.4\times {{10}^{-4}}{{m}^{3}}$ at normal temperature and constant normal pressure of $1\times {{10}^{5}}N/{{m}^{2}}$
	A Container having 1 mole of a gas at a temperature 27°C has a movable piston which maintains at constant pressure in container of 1 atm. The gas is compressed until temperature becomes 127°C. The work done is (Cp for gas is 7.03 cal/mol–K)
	In a reversible isochoric change
	Entropy of a thermodynamic system does not change when this system is used for
	The work done in which of the following processes is zero
	In which thermodynamic process, volume remains same
	In an isochoric process if ${{T}_{1}}={{27}^{o}}C$ and ${{T}_{2}}={{127}^{o}}C,$ then ${{P}_{1}}/{{P}_{2}}$ will be equal to
	Which is incorrect
	Which relation is correct for isometric process
