Kinetic Theory ...

Find the approx. number of molecules contained in a Vessel of volume 7 litres at $$ 0^0 C\ at\ 1.3 \times 10^5 $$ pascal:

The quantity $$\dfrac{PV}{kT}$$ represents

Which of the following parameters is the same for molecules of all gases at a given temperature?

Heat is added to an ideal gas and the gas expands. In such a process the temperature: 

A lead bullet just melts when stopped by an obstacle. Assuming that 25% of heat is absorbed by the obstacle, find the minimum velocity of the bullet if its initial temperature is $$27^{0}C$$ (melting point of lead $$327^{0}C$$; specific heat of lead $$= 0.03 \space cal/g^{0}C$$; latent heat of fusion of lead = 6 cal/g and J = 4.2 J/cal)

Postulate of kinetic theory is

The temperature of an ideal gas is kept constnat as it expands. The gas does external work. During this process, the internal energy of the gas

Molecules of a gas behave like 

Heat is not being exchanged in a body. If its internal energy is increased then

The internal energy of an ideal gas depends upon
