An ideal Carnot heat engine with an efficiency of $30\%$.It absorbs heat from a hot reservoir at $727^o C$. The temperature of the cold reservoir is .... $^oC$
The temperature inside a refrigerator is $t_2 \,^o C$ and the room temperature is $t_1\,^o C.$ The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be
At ${27^o}C$ a gas is suddenly compressed such that its pressure becomes $\frac{1}{8}th$ of original pressure. Temperature of the gas will be $(\gamma = 5/3)$
When heat energy of $1500\; Joules$, is supplied to a gas at constant pressure $2.1 \times {10^5}\;N/{m^2}$, there was an increase in its volume equal to $2.5 \times {10^{ - 3}}\;{m^3}$. The increase in internal energy of the gas in Joules is ...... $J$
Following figure shows two processes $A$ and $B$ for a gas. If $\Delta Q_A$ and $\Delta Q_B$ are the amount of heat absorbed by the system in two cases, and $\Delta U_A$ and $\Delta U_B$ are changes in internal energies, respectively, then
An ideal gas undergoes cyclic process as shown in density pressure graph. During the process $AB$ the work done $|W_{AB}| = 70\,J$ . During the process $BC$, the gas absorbs $150\,J$ of heat. During the process $CA$ , gas undergoes expansion and does $210\,J$ of work
An engine runs between a reservoir at temperature $200 \,K$ and a hot body which is initially at temperature of $600 \,K$. If the hot body cools down to a temperature of $400 \,K$ in the process, then the maximum amount of work that the engine can do (while working in a cycle) is (the heat capacity of the hot body is $1 \,J / K )$
