A liquid is in equilibrium with its vapour at its boiling point. On the average the molecules in the two phase have equal:
1 Inter-molecular forces
2 Potential energy
3 Total energy
4 Kinetic energy
Explanation:
Have equal K.E.

Rate of evaporation depends upon I. Nature of liquid II. Surface area of the liquid III. Temperature IV. Flow of air current over the surface
1 I and II
2 II and III
3 I, II and III
4 I, II, III and IV
Explanation:
All are the factors influencing vapour pressure

Assertion : At the same temperature, water has higher vapour pressure than acetic acid. Reason : Hydrogen bonding in water is weaker than in acetic acid.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Water's higher vapor pressure compared to acetic acid at the same temperature is due to water's weak intermolecular forces and extensive hydrogen bonding, facilitating a greater tendency for water molecules to escape into the vapor phase. So option (1) is correct.
