An ideal monoatomic gas is taken round the cycle $ABCDA$ shown in the $PV$ diagram in the given fig. The work done during the cycle is
$\frac{1}{2}PV$
$2\;PV$
$PV$
$Zero$
If coefficient of performance of a refrigarator is $\beta $ and heat absorbed from refrigarated space is $Q$, then work done on the system is
In an adiabatic expansion the product of pressure and volume.
A termodynamic system is taken through the closed cycle $PQRSP$ process. The net work done by the system is ...... $J$
Six moles of an ideal gas performs a cycle shown in figure. If the temperature are $T_A = 600\,K,\,\,T_B = 800\,K,\,\,T_C = 2200\,K$ and $T_D = 1200\,K,$ the work done per cycle is...... $kJ$
Helium gas goes through a cycle $ABCDA$ (consisting of two isochoric and two isobaric lines) as shown in figure. Efficiency of this cycle is nearly ..... $\%$ (Assume the gas to be close to ideal gas)
