Kinetic Theory ...

The amount of heat energy required to raise the temperature of 1 g of Helium at NTP, from $$T_{1}K$$ to $$T_{2}K$$ is

The ratio of the specific heats $$\dfrac {C_p}{C_v}=\gamma$$ in terms of degree of freedom (n) is given by:

A given sample of an ideal gas occupies a volume V at a pressure P and absolute temperature T. The mass of each molecule of the gas is m. which of the following gives the density of the gas?

Degree of freedom for polyatomic gas is

A vessel of volume $$20\ L$$ contains a mixture of hydrogen and helium at temperature of $$27^{\circ}C$$ and pressure $$2\ atm$$. The mass of mixture is $$5\ g$$. Assuming the gases to be ideal, the ratio of mass of hydrogen to that of the helium in the given mixture will be

The gas law $$\left [ \dfrac{PV}{T} \right ]=$$ constant is true for

The temperature of a gas contained in a closed vessel is increased by 2 K when the pressure is increased by 2%. The initial temperature of the gas is :

The mass of oxygen gas (in Kilo grams) occupying a volume of 11.2 litre at a temperature 27$$^{0}$$C and a pressure of 76cm of mercury is :

(Molecular weight of oxygen = 32)

From what minimum height, a block of ice has to be dropped in order that it may melt completely on hitting the ground :

If for a gas $$\dfrac{R}{C_{v}}=0.67$$, then the gas is made up of molecules which are :
