What happens to the atoms in water molecules when heat is added?

• The atoms expand and move faster, and as water becomes gas, the atoms change shape.

• The atoms condense and move slower, and as water becomes solid, the atoms get smaller.

• The atoms move faster at first, but as water becomes gas, the atoms keep the same speed.

• The atoms condense and move slower, but as water becomes solid, the atoms keep the same speed.
