When air in a syringe is compressed such that there is no change in temperature, the
air liquefies
pressure increases
intermolecular space increases
density decreases
Explanation
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.
