Kinetic Theory ...

One mole of a gas at a pressure 2 Pa and temperature 27$$^o$$C is heated till both pressure and volume are doubled. What is the temperature of the gas?

What is number of degrees of freedom of an ideal diatomic molecule at ordinary temperature?

The internal energy of air in a room of volume 50 m$$^3$$ at atmospheric pressure will be

If the value of R = 2/5 C$$_v$$ for a gas, then the atomicity of the gas will be:

Which of the following quantities is zero on an average for the molecules of an ideal gas in equilibrium?

The total kinetic energy of 8 litres of helium molecules at 5 atmosphere pressure will be

The Avogadro's number when to tends to infinity, the phenomenon of Brownian motion would

A product from a chemical industry passes through three states - gas, liquid, solid. The product is initially formed in gaseous state which is then liquefied and finally solidified. For same mass (say 5g) which state has maximum internal energy?

The temperature of an ideal gas is increased from 27$$^o$$C to 927$$^o$$C. Then, the mean kinetic energy of gas molecules :

In two vessels of the same volume, atomic hydrogen and helium with pressure 1 atm and 2 atm are filled. If temperature of both the same is the same, then the average speed of hydrogen atom $$v_H$$ will be related to helium $$v_{He}$$ as
