Which of the following would increase the volume of a gas? a. chilling a can of soda b. heating a hot-air balloon c. squeezing a balloon d. pressurizing an air tank

According to Ideal Gas Equation, Volume is related to Pressure and Temperature as follow,

                                    P V  =  n R T
Or,
                                       V  =  n R T / P

This relation shows that Volume is directly related to Temperature and Inversely related to pressure. So,

A.Chilling a can of soda: As temperature is decreased so the volume will also decrease.

B.Heating a hot-air balloon: As temperature is increased, so Volume will also increase.

C.Squeezing a balloon: As pressure is applied, so volume will decrease.

D.Pressurizing an air tank: Again pressure is applied so volume will decrease.
