50 ml of gas A diffuses through a membrane in the same time as for the diffusion of 40 ml of a gas B under identical pressure- temperature conditions. If the molecular weight of A is 64 that of B would be
X ml of H₂ gas effuses through a hole in a container in 5 seconds. The time taken for the effusion of the same volume of the gas specified below under identical condition is
If the absolute temperature of a gas is doubled and the pressure is reduced to one-half, the volume of the gas will
How many O₂ molecules are present in 2.0 L of oxygen gas at 27 °C temperature and 3.0 atm pressure ?
If the pressure is tripled and temperature (in kelvins) is halved, the volume of a given mass of an ideal gas becomes
A flask containing air (open to atmosphere) is heated from 300 K to 500 K. The percentage of air escaped to the atmosphere is nearly
An open flask contains air at 27 °C temperature and one atm pressure. The flask is heated to 127 °C at the same pressure. What fraction of the original air will remain in the flask?
For V versus T plot at constant pressure P₁ and P₂ for an ideal gas is given in adjoining figure. Which of the following relation is correct ?
Assertion :Kinetic energy and momentum of ideal gas molecules are conserved during intermolecular collision. Reason :Collision among real gas molecules is inelastic.
Assertion: For a real gas, the gas pressure is always less than the pressure calculated from kinetic theory of gases. Reason: In kinetic theory, both molecular volumes and intermolecular attractions were ignored.
