At room temperature the forces of attraction between the particles of solid substances are___than those which exist in the gaseous state.

At room temperature the forces of attraction between the particles of solid substances are stronger than those which exist in the gaseous state.

Explanation

  • The forces of attraction between the particles of a gas are minimum, intermediate in case of a liquid and are maximum in a solid.
  • Hence, in case of oxygen ‘forces of attraction’ are minimum since it is a gas.
  • On increasing the temperature of solids, the kinetic energy of the particles increases.
  • Due to the increase in kinetic energy, the particles start vibrating with greater speed.
  • The energy supplied by heat overcomes the forces of attraction between the particles.
  • The particles leave their fixed positions and start moving more freely.
