Question

Why " The evaporated vapours exert more pressure and this pressure becomes equal to external pressure. " ??

Answer 1

because when matter is in gaseous state its particles movement is fastest so they exert more pressure

Answer 2

this why because we know that air has less intermolecular spaces and thus this less intermolecular spaces help them to exert a high amount of pressure on the both of the sides internal as well as external . as we know that external environment is full of air and thus the vapours can exert the same amount of pressure as in outside.
