During which of the following thermodynamic process represented by $P V$ diagram the heat energy absorbed by system may be equal to area under $P V$ graph?
Two identical vessels $A \& B$ contain equal amount of ideal monoatomic gas. The piston of $A$ is fixed but that of $B$ is free. Same amount of heat is absorbed by$A \& B$. If $B'$s internal energy increases by $100 \,\,J$ the change in internal energy of $A$ is ...... .$J$
A gas ($\gamma = 1.3)$ is enclosed in an insulated vessel fitted with insulating piston at a pressure of ${10^5}\,N/{m^2}$. On suddenly pressing the piston the volume is reduced to half the initial volume. The final pressure of the gas is
In the $p-V$ diagram below, the dashed curved line is an adiabat.For a process that is described by a straight line joining two points $X$ and $Y$ on the adiabat (solid line in the diagram) heat is (Hint consider the variation in temperature from $X$ to $Y$ along the straight line)
A Carnot engine whose low temperature reservoir is at $7\,°C$ has an efficiency of $50\%$. It is desired to increase the efficiency to $70\%$. By how many degrees should the temperature of the high temperature reservoir be increased ....... $K$
