Answer: difference in Vander Waals forces

Explanation:

The intermolecular force of attraction between the molecules in chlorine is WEAKER than that of Bromine.

This force is known as VANDER WAALS forces. And it DECREASES down the group; so Chlorine which is placed higher is a GAS, while Bromine placed lower in Group 7 is a LIQUID.
