An ideal gas at a pressures of $1$ atmosphere and temperature of ${27^o}C$ is compressed adiabatically until its pressure becomes $8$ times the initial pressure, then the final temperature is ..... $^oC$ ($\gamma = 3/2$)
An ideal monoatomic gas with pressure $P$, volume $V$ and temperature $T$ is expanded isothermally to a volume $2\, V$ and a final pressure $P_i$. If the same gas is expanded adiabatically to a volume $2\,V$, the final pressure is $P_a$ . The ratio $\frac{{{P_a}}}{{{P_i}}}$ is
Consider the given series combination of carnot cycles. If $W_1 = W_2$ then the value of $T$ is ...... $K$ (all temperatures are maintained at their respective values)
The temperature inside and outside a refrigerator are $273 \,K$ and $300 \,K$ respectively. Assuming that the refrigerator cycle is reversible, for every joule of work done, the heat delivered to the surrounding will be nearly ........ $J$
Two ideal Carnot engines operate in cascade (all heat given up by one engine is used by the other engine to produce work) between temperatures, $\mathrm{T}_{1}$ and $\mathrm{T}_{2} .$ The temperature of the hot reservoir of the first engine is $\mathrm{T}_{1}$ and the temperature of the cold reservoir of the second engine is $\mathrm{T}_{2} . T$ is temperature of the sink of first engine which is also the source for the second engine. How is $T$ related to $\mathrm{T}_{1}$ and $\mathrm{T}_{2}$, if both the engines perform equal amount of work?
A diatomic gas with rigid molecules does $10\, J$ of work when expanded at constant pressure. What would be the heat energy absorbed by the gas, in this process ..... $J$.
