The total kinetic energy associated with n moles of monoatomic gas is

A Carnot engine working between the temperature 500 K and 1000 K does a work of 1000 J. The heat energy supplied by the source to the engine per cycle is

Consider a process on a system shown in figure below. During the process, the work done by the system

The correct graph between loge^R and loge(θ– θ₀) during cooling of a body may be (R is the rate of cooling and q0 is surrounding temperature)

Heat required to raise the temperature of 5.4 g of aluminum from ${35}^{0}C$ to ${65}^{0}C$ is (Molar heat capacity of $AI=24Jmo{l}^{-1}{K}^{-1}$ )

If equilibrium constant $K_c$ for a reaction is ${10}^{10}$ at ${27}^{0}C$ , then $?G^0$ of the reaction at ${27}^{0}C$  will be

For the reaction, $2Cl\left(g\right)-?C{l}_2\left(g\right)$ , the sign of $?H$ and $?S$  respectively are

A cannot engine works as a refrigerator between $250K$ and $300K$ . It receives $500cal$ heat from the reservoir at the lower temperature. The amount of work done in each cycle to operate the refrigerator is nearly

Which of the following is correct for a reaction to be spontaneous?
