Question

At a fixed amount of gas at constant temperature T occupying volume V1at pressure P1 undergoes expansion so that the volume becomes V2 and the pressure becomes P2 what will be the expression for this?

  1. P1V= P2V2
  2. P subscript 1 over V subscript 2 equals P subscript 2 over V subscript 2
  3. P subscript 1 over V subscript 1 equals P subscript 2 over V subscript 2
  4. P subscript 1 V subscript 2 space equals space P subscript 2 V subscript 1

hintHint:

The relation of temperature, volume and pressure is given by Boyle's law.

The correct answer is: P1V= P2V2


    The correct option is a)P1V1 = P2V2.
    At constant temperature the product of initial pressure and initial volume is equal to the product of final pressure and final volume. This is boyle's law.
