The diagram illustrates a rubber toy containing air. When a child sits on the toy, its volume becomes smaller. The air inside the toy stays at the same temperature. How does the pressure of the air in the toy change, and what is the reason?
- Apressure decreases; air molecules move more slowly
- Bpressure decreases; air molecules strike the rubber less frequently
- Cpressure increases; air molecules move more quickly
- Dpressure increases; air molecules strike the rubber more frequently
