When air in a syringe is compressed such that there is no change in temperature, the

  • A air liquefies
  • B pressure increases
  • C intermolecular space increases
  • D density decreases

The correct answer is B. pressure increases

Since the temperature of air remain constant.So, it is a isothermal process.

PV=K

This eq. shows that on increasing pressure, the volume gets reduced and vice-versa.

Since the syringe is slowly compressed, volume is decreasing.

Therefore, the pressure inside the syringe will increases because the molecules now hit the syringe walls more frequently.
