For clouds to form, water vapor in the air must condense and change from a gas to a liquid. what must water molecules do as part of this process? a. come close together and stick to each other b. escape into the surrounding air c. connect to each other in a rigid structure d. stop moving relative to each other

A.  

come close together and stick to each other

come close together and stick to each other

Explanation:

The difference between three phases of a matter is the intermolecular interactions and thermal energy.

In case of gas, the intermolecular interactions are weak and thermal energy is high. So molecule move randomly, far from each other.

However in case of liquids the force of interactions are relatively stronger and the molecules are held together more effectively than gas.

Thus in order to condense a gas, we have to make the molecule come closer to each other so that they can be converted to liquid.

you need to have a picture of the atom that way we can answer it
