Assertion : Carbanions like ammonia have pyramidal shape. Reason : The carbon atom carrying negative charge has an octet of electrons.
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 ?
NH₃ can be liquefied at ordinary temperature without the application of pressure. But O₂ cannot, because
Gases possess characteristic critical temperature which depends upon the magnitude of intermolecular forces between the particles. Following are the critical temperatures of some gases Gases : H₂ He O₂ N₂ Critical tem…
Assertion :For a given amount of an ideal gas, a plot of pressure (p) versus (1/V) is a straight line at a constant temperature. Reason :A given amount of an ideal gas at a constant temperature obeys Boyle’s law.

Five grams each of the following gases at 87 °C and 750 mm pressure are taken. Which of them will have the least volume ?
Assertion :Above critical temperature liquid state cannot be observed. Reason :Above critical temperature, the average kinetic energy of a molecule is always greater than the maximum kinetic energy a molecule can poss…
Assertion :Gases do not liquefy above their critical temperature, whatever the high pressure is applied. Reason :Above critical temperature, molecular speed is high and intermolecular force cannot hold the molecules t…
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.
Assertion :Kinetic energy and momentum of ideal gas molecules are conserved during intermolecular collision. Reason :Collision among real gas molecules is inelastic.
