Answer: 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.
The volume of the gas when temperature is constant is 6.25 L.
What is the relation between pressure and volume?
Relation between the pressure and volume of the gas by using the ideal gas equation will be represented as:
P₁V₁ = P₂V₂, where
P₁ & V₁ are the initial pressure and volume.
P₂ & V₂ are the final pressure and volume.
On putting values from the question, we get
V₂ = (100)(2.5) / (40) = 6.25 L
Hence required volume is 6.25 L.
