Solution

Explanation

  1. An ideal gas is a theoretical gas with zero inter-molecular force between many randomly moving point particles.
  2. Point particles are point mass with negligible volume. They do not attract or repel the adjacent molecules.
  3. In ideal gas is collisions between the inter molecules or inter atoms are perfectly elastic as well as there’s no intermolecular force of attraction
  4. Ideal gases follow a simplified equation of state called as ideal gas law. It is represented by four variables P, V, T as well as n constant.
  5. Ideal gas law relates volume of the gas (V), its pressure (P),to the number of moles of gas (n) and temperature (T) and ideal gas constant, R as

PV=nRT
