Intermolecular space is the average distance between the molecules of any element. The intermolecular interactions drive this space to grow or shrink. The molecules in gases are only loosely bonded. As a result, the intermolecular space of gases is maximized.

Factor influencing intermolecular space:

 Pressure: 

  • Raising pressure in a confined container causes gas compression.

  • As a result, increasing the pressure causes a decrease in the space between the molecules of the gas.

Volume (enclosed space/container):

  •  If the volume of the container is increased, the same quantity of gas may accommodate additional space.

  • As a result, the greater volume would result in an increase in intermolecular space.

Volume/amount of gas

  • If the volume of the gas drops but the volume of the container stays constant, more room for gas-particle accommodation is created.

  • Inter-molecular space is inversely proportional to the volume of the gas (assuming the volume of the container is constant). 

  • Hence decreased volume of gas would result in an increase of inter-molecular space.
