Answer:
Boly's law
Step-by-step explanation:
The given data show the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
This shows that when pressure of gas is increases the volume goes to decreases and vice versa.
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
when volume is 10.0 mL the pressure of gas was 760.0 torr.
When pressure goes to reduce i,e 191.0 torr the volume became 40.0 mL. This shows that volume and pressure are inversely proportional to each other.
