Answer» a) This is a correct statement. b) This statement is incorrect. Reason: Evaporation takes place at any temperature below its boiling point. c) This statement is incorrect. Correct Statement: The inter-particle space of solids is minimum. Explanation: The force of attraction between the particles is also very high due to less inter-particle space. Hence solids have definite shape and a fixed volume. d) This statement is incorrect Correct Statement: Gases have weakest inter-particle forces. Explanation: The inter-particle space for a gas is maximum. Hence the interparticle forces are also weak. Due to this gases have no definite shape or fixed volume. They have to be stored in a closed container always. |
