Decreasing the temperature can change water vapor into liquid water. what other change might also accomplish this task?
a. increasing the temperature
b. decreasing the pressure
c. increasing the pressure

Answer;

Increasing the pressure

Explanation;An increase in pressure on a gas can bring the molecules close enough to each other to develop some inter-molecular attractions and form a liquid.The increase in pressure changes the state of matter from gas to liquid and also from liquid to solid. But increase in pressure alone cannot change the state of matter. Every gases and liquid have certain temperature above which the application of pressure would not change the state of matter.
