Read the following statements and choose the correct option:

Assertion (A) Gas can be easily compressed by applying pressure.

Reason (R) When we apply pressure on a gas, the intermolecular space between the gaseous particles reduces and it gets compressed easily.

The correct answer is Both (A) and (R) are true and (R) is the correct explanation of (A).
 Key Points 

• On applying pressure, gas can be compressed easily.
  • ​This statement is true.
  • The gaseous state is the simplest state of matter.
  • Gases are highly compressible.
  • Gases exert pressure equally in all directions.
  • Gases have a much lower density than solids and liquids.
•  When we apply pressure to a gas, the intermolecular space between gaseous particles decreases and it gets compressed.
  • ​This statement is correct.
  • Intermolecular forces are the forces of attraction and repulsion between interacting particles (atoms and molecules).
  • Increasing the amount of space available will allow the gas particles to spread farther apart, but this reduces the number of particles available to collide with the container, so pressure decreases. 
  • Decreasing the volume of the container forces the particles to collide more often, so the pressure is increased.
  • A good example of this is when you fill a tire with air. As more air goes in, the gas molecules get packed together, reducing their volume. As long as the temperature stays the same, the pressure increases.
