Question

What happens to the molecules in a glass of water as the water evaporates?

They slow down.

They move faster.

They increase in volume.

They are destroyed.

Answer 1

It is evaporating into a gas, and they will move faster

Answer 2

They move faster.

Explanation:

Given that water evaporates in a glass of water.

We have to find the reaction of the molecules of water.

Whenever evaporation happens to liquid substance water, the liquid is converted into gas. So when water evaporates, the molecules start to move quickly so that they escape into the atmosphere as molecules of water vapour.

Hence answer b) they move faster is right.
