In a process, temperature and volume of one mole of an ideal monoatomic gas are varied according to the relation $VT = K$, where $I$ is a constant. In this process the temperature of the gas is increased by $\Delta T$. The amount of heat absorbed by gas is ($R$ is gas constant)
Two moles of an ideal monoatomic gas at ${27^o}C$ occupies a volume of $V.$ If the gas is expanded adiabatically to the volume $2V,$ then the work done by the gas will be ....... $J$ $[\gamma = 5/3,\,R = 8.31J/mol\,K]$
In a thermodynamics process, pressure of a fixed mass of a gas is changed in such a manner that the gas releases $20\,J$ of heat and $8\,J$ of work is done on the gas. If the initial internal energy of the gas was $30\,J$. The final internal energy will be...... $J$
A refrigerator consumes an average $35\, {W}$ power to operate between temperature $-10^{\circ} {C}$ to $25^{\circ} {C}$. If there is no loss of energy then how much average heat per second does it transfer? (in ${J} / {s}$)
One mole of a monatomic ideal gas undergoes an adiabatic expansion in which its volume becomes eight times its initial value. If the initial temperature of the gas is $100 K$ and the universal gas constant $R =8.0 Jmol ^{-1} K ^{-1}$, the decrease in its internal energy, in Joule, is. . . . .
$Assertion :$ When a bottle of cold carbonated drink is opened, a slight fog forms around the opening.
$Reason :$ Adiabatic expansion of the gas causes lowering of temperature and condensation of water vapours.
