A gas behaves more closely like an ideal gas at

If T represents the absolute temperature of an ideal gas, the volume coefficient of thermal expansion at constant pressure is proportional to:

A sample of an ideal gas is contained in a cylinder. The volume of the gas is suddenly decreased. A student makes the following statements to explain the change in pressure of the gas.
I. The average kinetic energy of the gas atoms increases.
II. The atoms of the gas hit the walls of the cylinder more frequently.
III. Temperature of the gas remains unchanged.
Which of these statements is true?

A certain mass of an ideal gas undergoes a reversible isothermal compression. Its molecules, compared with the initial state, will then have the same
(i) root mean square velocity
(ii) mean momentum
(iii) mean kinetic energy

The number of air molecules in a ( 5m x 5m x 4m ) room at standard temperature and pressure is of the order of :

The mean kinetic energy of a gas molecule is proportional to 

Which of the following statement is incorrect for gases?

The internal energy of a gas:

When the temperature is increased from 0$$^o$$C to 273$$^o$$C, in what ratio the average kinetic energy of molecules changes?
