A

the gas molecules are adsorbed at the surface

B

the gas molecules concentrate at the surface of the charcoal

C

the gas molecules are adsorbed at the surface

D

the gas molecules are desorbed by the surface

An ideal gas at pressure P and temperature T is enclosed in a vessel of volume V. Some gas leaks through a hole from the vessel and the pressure of the enclosed gas falls to P'. Assume that the temperature of the gas remains constant during the leakage. What is the number of moles of the gas that have leaked ?

The initial temperature of a gas is 100^(@)C . The gas is contained in closed vessel . If the pressure of the gas is increased by 5% , calculate the increase in temperature of the gas :

When a gas is heated in a vessel of constant volume , the pressure increases because

Pressure of a gas in a vessel can be measured by

A gas is kept in an enclosure. The pressure of the gas is reduced by pumping out some gas. Will the temperature of the gas decreases by Charles's law?
