Answer 2

Elastic constraint

Explanation:

• Atoms and molecules in a gas are widely separated as the force of attraction between them is quite weak.
• The collisions between the gas particles and container walls are elastic collisions.  
• Due to the compressibility and expandability of gas, molecules take the shape of the container in which they are placed.
