Question

what would cause water to turn from a gas to a liquid?
a decreasing the waters temperature
b increasing the waters temperature
c increasing the waters mass
d none of the above

Explanation:

Water changes from a gas (water vapor) to a liquid (water) through the process of condensation. Condensation occurs when the temperature of the water vapor is decreased, causing the water molecules to slow down and come together to form liquid droplets. Changing the mass of water does not directly cause the phase - change from gas to liquid, and increasing the temperature would lead to more evaporation or keep it in a gaseous state.

Answer:

a. decreasing the water's temperature
