Question 68

The plunger of a sealed syringe containing a fixed mass of air is pulled outwards, increasing the volume of the trapped air.

B

decreases because air molecules move more slowly

C

increases because air molecules strike the walls of the syringe more frequently

D

increases because air molecules move more quickly
