A. air liquefies
B. pressure increases
C. intermolecular space increases
D. density decreases
Correct Answer:
Option B – pressure increases
Explanation
Since the temperature of air remains constant. So, it is an isothermal process.
PV=K
This eq. shows that on increasing pressure, the volume gets reduced and vice-versa.
Since the syringe is slowly compressed, the volume is decreasing.
Therefore, the pressure inside the syringe will increases because the molecules now hit the syringe walls more frequently.
