The pressure on 2.50 l of gas changes from 100 kpa to 40 kpa. what is the new volume of the temperature is constant?

6.25 L (6L if sig figs)

Explanation:

The relationship between pressure and volume is inverse when temperature is constant, where P1V1=P2V2

P1 = 100

P2 = 40

V1 = 2.5

Plug in to get 100(2.5) = 40v2

Solve for v2 = 250/40 = 6.25 L

This makes sense because if the pressure decreases the volume increases.

if your teacher has you do sig figs and you kept the sig figs from the problem, then there should be 1 sig fig (from 40 kPa) so the answer would be 6 L.
