If water is evaporated and changed from a liquid to a gas, what must happen to the water molecules during the process? (*hint: think about the arrangement of particles in the liquid and gas phases and what type of movement would occur)*
A. they escape into the surrounding air
B. they connect into a rigid structure
C. come close together and stick to each other

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.

How does the motion of particles in a gas change as the gas cools

All motion is caused by force? true or false
