Concept explainers
Interpretation:
The reason for gasses to be easier to compress than solids needs to be explained.
Concept introduction:
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.

Answer to Problem 85A
The larger space between particles and weak intermolecular attraction of gas makes it easier to compress it easily.
Explanation of Solution
The space between the gas particles is very large and the size of particles is very small. Due to small size of particle the force of attraction between particles is very low or negligible while solid and liquid particles are densely packed.
More over the larger space between particles of gas makes it easier to compress it easily.
The larger space between particles of gas makes it easier to compress it easily.
