The work of $146\,kJ$ is performed in order to compress one kilo mole of a gas adiabatically and in this process the temperature of the gas increases by $7\,^oC$ . The gas is $(R = 8.3\, J\, mol^{-1}\, K^{-1})$
A polyatomic gas $\left( {\gamma = \frac{4}{3}} \right)$ is compressed to $\frac{1}{8}$ of its volume adiabatically. If its initial pressure is ${P_o}$, its new pressure will be
Two cylinders contain same amount of ideal monatomic gas. Same amount of heat is given to two cylinders. If temperature rise in cylinder $A$ is $T_0$ then temperature rise in cylinder $B$ will be .........
A perfect gas of a given mass is heated first in a small vessel and then in a large vessel, such that their volumes remain unchanged. The $P-T$ curves are
Suppose ideal gas equation follows $V{P^3}$= constant. Initial temperature and volume of the gas are $T$ and $V$ respectively. If gas expand to $27V$ then its temperature will be come
The latent heat of vaporisation of water is $2240\, J/gm$. If the work done in the process of expansion of $1 \,g$ is $168 \,J$, then increase in internal energy is ....... $J$
Consider the efficiency of Carnot's engine is given by $\eta=\frac{\alpha \beta}{\sin \theta} \log _{e} \frac{\beta x}{k T}$, where $\alpha$ and $\beta$ are constants. If $T$ is temperature, $k$ is Boltzman constant, $\theta$ is angular displacement and $x$ has the dimensions of length. Then, choose the incorrect option.
