For an ideal heat engine, the temperature of the source is $127\,^{\circ} C$. In order to have $60\, \%$ efficiency the temperature of the sink should be $........\,{ }^{\circ} C$. (Round off to the Nearest Integer)
Suppose that two heat engines are connected in series, such that the heat released by the first engine is used as the heat absorbed by the second engine, as shown in figure. The efficiencies of the engines are $\epsilon_1$ and $\epsilon_2$, respectively. The net efficiency of the combination is given by :
In a heat engine, the temperature of the source and sink are $500\, K$ and $375\, K$. If the engine consumes $25\times10^5\, J$ per cycle, the work done per cycle is
Two identical containers $A$ and $B$ with frictionless pistons contain the same ideal gas at the same temperature and the same volume $V$. The mass of the gas in $A$ is ${m_A}$ and that in $B$ is ${m_B}$. The gas in each cylinder is now allowed to expand isothermally to the same final volume $2V$. The changes in the pressure in $A$ and $B$ are found to be $\Delta P$ and $1.5 \Delta P$ respectively. Then
A van der Waal's gas obeys the equation of state $\left(p+\frac{n^2 a}{V^2}\right)(V-n b)=n R T$. Its internal energy is given by $U=C T-\frac{n^2 a}{V}$. The equation of a quasistatic adiabat for this gas is given by
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 ....... $K$
A given mass of a gas expands from a state $A$ to the state $B$ by three paths $1, 2$ and $3$ as shown in $T-V$ indicator diagram. If $W_1, W_2$ and $W_3$ respectively be the work done by the gas along the three paths, then
