Why do gases diffuse faster than liquids? gas particles have more kinetic energy a liquid does not have as many particles liquids have less volume to diffuse through liquids have more pressure to overcome when diffusing

Gases have more kinetic energy

Option (a) is the correct answer.

Explanation:

Particles of a gas are held by weak Vander waal forces due to which they have more kinetic energy. This leads to more number of collisions between gas particles.

As a result, gases readily diffuse in their surroundings.

On the other hand, molecules of a liquid are more closer as compared to molecules of a gas. So, they have less kinetic energy as compared to gas molecules. Hence, liquids are not able to diffuse into their surroundings.

Thus, we can conclude that gases diffuse faster than liquids because gas particles have more kinetic energy.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
