Sam was investigating a container of water. Water can be a solid, liquid, or gas. At first, Sam said the water molecules were moving around each other. Later, the water molecules were moving in place. What change did they observe to the water? At first, the water was a gas. Later, it was a liquid.
At first, the water was a liquid. Later, it was a solid.
At first, the water was a solid. Later, it was a liquid.
At first, the water was a liquid. Later, it was a gas.

A) At first, the water was a gas. Later, it was a liquid.

Explanation:

The molecules of a solid cant move at all, so therefore we can knock out B and C. Moleculaes move more freely in a gas form than in a water form, so therefore the firt form has to be a gas, so knock out the answer choice D, which keaves you with A. I hope this helps :)

At first, the water was a gas. Later, it was a liquid.

Explanation:

i think the answer is a, hope this is right, that would be my best guess.

correct it is c.) b b
