Given diagram shows an ideal gas taken from state $1$ to $2$ through optional paths, $A,B,C.$ Let $Q,W$ and $U$ represent the heat supplied to, the work done by gas and the internal energy of the gas, respectively. Then which of the following conditions is true?
$Q_A < Q_B < Q_C$
$W_A>W_B> W_C$
$U_1 -U_2= Q_A-W_A$
$Q_A-W_A< Q_B-W_B< Q_C-W_C$
$Assertion :$ The isothermal curves intersect each other at a certain point.
$Reason :$ The isothermal changes takes place rapidly, so the isothermal curves have very little slope.

Which of the following graphs correctly represents the variation of $\beta = - \left( {\frac{{dV}}{{dP}}} \right)/V$ with $P$ for an ideal gas at constant temperature ?
Given diagram shows an ideal gas taken from state $1$ to $2$ through optional paths, $A, B, C$ . Let $Q, W$ and $U$ represent the heat supplied to the gas, work done by the gas, and the internal energy of the gas, respectiely, then which of the following conditions is true?
The efficiency of Carnot engine is $50\%$ and temperature of sink is $500\,K.$ If the temperature of source is kept constant and its efficiency is to be raised to $60\%$ then the required temperature of sink will be ........... $\mathrm{K}$
