When $x$ amount of heat is given to a gas at constant pressure, it performs $x/3$ amount of work. The average number of degrees of freedom per molecule is
The specific heat of the mixture of two gases at constant volume is $\frac {13}{6}\,R$ . The ratio of number of moles of first gas to second is $1 : 2$. The respective gases may be
A gas mixture consists of molecules of type $1, 2$ and $3$, with molar masses ${m_1} > {m_2} > {m_3}.$ ${V_{rms}}$ and $\overline K $ are the $r.m.s.$ speed and average kinetic energy of the gases. Which of the following is true
An object is placed in a medium of refractive index $3$. An electromagnetic wave of intensity $6 \times 10^8 \mathrm{~W} / \mathrm{m}^2$ falls normally on the object and it is absorbed completely. The radiation pressure on the object would be (speed of light in free space $=3 \times 10^8 \mathrm{~m} / \mathrm{s}$ ):
$310\,J$ of heat is required to raise the temperature of $2\,moles$ of an ideal gas at constant pressure from $25\,^oC$ to $35\,^oC$ . The amount of heat required to raise the temperature of the gas through the same range at constant volume is .... $J$
The $rms$ speeds of the molecules of Hydrogen, Oxygen and Carbondioxide at the same temperature are ${V}_{{H}}, {V}_{0}$ and ${V}_{{C}}$ respectively then
