$Assertion :$ 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.
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
If the Assertion is correct but Reason is incorrect.
If both the Assertion and Reason are incorrect.
Three moles of an ideal monatomic gas performs a cyclic process as shown in the figure. The temperatures in different states are $T_1 = 400\,K, T_2 = 800\,K, T_3 = 2400\,K$ and $T_4 = 1200\,K$. Determine the work done by the gas during the cycle .... $kJ$ [Given $R = 8.31\, J-mole^{-1}K^{-1}$)
If the door of a refrigerator is kept open, then which of the following is true
In thermodynamic process pressure of a fixed mass of gas is changed in such a manner that the gas releases $30$ joule of heat and $18$ joule of work was done on the gas. If the initial internal energy of the gas was $60$ joule, then, the final internal energy will be ..... $J$
Six moles of an ideal gas perfoms cycle shown in figure. If the temperature $T_A = 600\, K$, $T_B = 800\, K, T_C = 2200\, K$ and $T_D = 1200\, K$, the work done per cycle is........ $kJ$
$P-V$ diagram of $2\,g$ of $He$ gas for $A \to B$ process is shown. What is the heat given to the gas ?
