Interpretation:
The density of mercury is higher than that of water at same temperature and pressure. This is to be explained in terms of intermolecular forces and the kinetic molecular theory.
Concept introduction:
Intermolecular forces are those forces which keep on holding two atoms together in a molecule
The Kinetic Molecular Theory is used to explain the nature of matter.
- The particles which are always in motion the matter is made-up with these particles. Their energy due to motion is called kinetic energy.
- The kinetic energy in a substance is directly related to its temperature.
- The space in between particles is related to the substance's
state of matter . - The force of attraction in between particles called intermolecular forces.
Explanation of Solution
The intermolecular force between mercury atoms is higher as compare to water and the kinetic energy of mercury particle is less as compare to water so the density of mercury is higher than that of water at same temperature and pressure.
