An ideal monoatomic gas is taken round the cycle $ABCDA$ as shown in the following $P-V$ diagram. The work done during the cycle is

An ideal gas undergoes a cyclic process as shown in the diagram. The net work done by the gas in the cycle is

An ideal gas is made to undergo the cyclic process shown in the figure below. Let $\Delta W$ depict the work done,$\Delta U$ be the change in internal energy of the gas,and $Q$ be the heat added to the gas. The signs of each of these three quantities for the whole cycle will be ($0$ refers to no change):

$A$ quantity of monoatomic gas undergoes a process in which pressure is changed linearly with volume. The pressure and volume are changed from initial value $(P_{o}, V_{o})$ to final value $(3 P_{o}, 3 V_{o})$. The heat absorbed by the gas during the process is (in $P_{o} V_{o}$)

The magnitude of heat exchanged by a system for the given cyclic process $ABCA$ (as shown in the figure) is (in $SI$ units).

The heat absorbed by a system in going through the given cyclic process is: (in $\,J$)
