Question

Give reasons:- A gas fills completely the vessel in which it is kept.

Solution 1

There is little attraction between particles of gas. Thus, gas particles movefreely in all directions. Therefore, gas completely fills the vessel in which it is kept.

Solution 2

The molecules of gas have high kinetic energy due to which they keep moving in all directions and hence fill the vessel completely in which they are kept.

  Is there an error in this question or solution?
