Question:
The rate of difusion is
The rate of difusion is
Updated On: Sep 4, 2024
- faster in solids than in liquids and gases
- faster in liquids than in solids and gases
- equal to solids, liquids and gases
- faster in gases than in liquids and solids.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
: Rate of diffusion, $ r\propto \sqrt{\rho } $ where p is the density. As density is least of gases than solids and liquids, hence rate of diffusion of gases is faster than in liquids and solids.

Gas Laws
The gas laws were developed at the end of the 18th century, when scientists began to realize that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
The five gas laws are:
- Boyle’s Law, which provides a relationship between the pressure and the volume of a gas.
- Charles’s Law, which provides a relationship between the volume occupied by a gas and the absolute temperature.
- Gay-Lussac’s Law, which provides a relationship between the pressure exerted by a gas on the walls of its container and the absolute temperature associated with the gas.
- Avogadro’s Law, which provides a relationship between the volume occupied by a gas and the amount of gaseous substance.
- The Combined Gas Law (or the Ideal Gas Law), which can be obtained by combining the four laws listed above.
