One mole of an ideal gas undergoes two different cyclic processes I and II, as shown in the $P-V$ diagrams below. In cycle I, processes $a, b, c$ and $d$ are isobaric, isothermal, isobaric and isochoric, respectively. In cycle II, processes $a^{\prime}, b^{\prime}, c^{\prime}$ and $d^{\prime}$ are isothermal, isochoric, isobaric and isochoric, respectively. The total work done during cycle I is $W_I$ and that during cycle II is $W_{I I}$. The ratio $W_I / W_{I I}$ is . . . .
An ideal gas is taken through the cycle $A \to B \to C \to A$ , as shown in the figure. If the net heat supplied to the gas in the cycle is $5\ J$, the work done by the gas in the process $C \to A$ is .... $J$
The efficiency of carnot engine is $50\%$ and temperature of sink is $500\;K$. If temperature of source is kept constant and its efficiency raised to $60\%$, then the required temperature of the sink will be
A Carnot engine with efficiency $50\,\%$ takes heat from a source at $600\,K$. In order to increase the efficiency to $70\,\%$, keeping the temperature of sink same, the new temperature of the source will be $.........\,K$
An ideal gas is taken from point $A$ to point $C$ on $P-V$ diagram through two process $AOC$ and $ABC$ as shown in the figure. Process $AOC$ is isothermal
$n-$ $moles$ of an ideal gas with constant volume heat capacity $C_v$ undergo an isobaric expansion by certain volume. The ratio of the work done in the process, to the heat supplied is
