What is the effect of pressure on gas:
  • A
    Volume of gas decreases with increase in pressure
  • B
    Volume of gas increases with increase in pressure
  • C
    Both a and b
  • D
    Pressure has no effect on gas
✓

Answer

  1.  Volume of gas decreases with increase in pressure

Exaplantion:

The volume of gas decreases with an increase in pressure.

This leads to the conversion of the gaseous state into a liquid state and eventually into a solid-state.

The volume of the gas decreases by applying pressure on gases because gases are compressible.
