Use of hot air balloons in sports and for meteorological observations is an application of

Kinetic theory of gases presumes the collision between the molecules to be perfectly elastic because:

Air at sea level is dense. This is a practical application of

The temperature of a gas is raised from 27^oC to 927^oC. The root mean square speed

If 20 L of a gas at 1 atm is expanded to 50 L at constant T, then what is the final pressure?

When the temperature of 23ml of dry CO₂​ gas is changed from 10^∘ to 30^∘ at constant pressure of 760 mm, the volume of gas becomes closest to which one of the following?

The pressure of 2 moles of ideal gas at 546K having volume 44.8L is:

Equal volumes of two gases which do not react together are enclosed in separate vessels. Their pressure are 100mm and 400 mm respectively. If the two vessels are joined together, then what will be the pressure of the resulting mixture ( temperature remaining constant )
