Question

A syringe has a volume of 10 cm^3 at pressure 1 atm . If you plug the end so that no gas can escape and push the plunger down . What must be the final volume to change the pressure to 3.5 atm

Answer 1

using P1V1=P2V2,

that is boyles law

where P1= 1atm , V1=10cc which is. equal to 10ml hence 0.1litres

and P2= 3.5atm . we need to find V2

0.1*1=3.5*V2

V2= 0.02857litres

so the answer is 0.02857 L

Answer 2

Answer: is 2.9 cm^3

Explanation:

Given: P1 = 1 ATM ,V1= 10.0 cm^3

P2= 3.5 ATM , V2= ?

According to Boyle's law,

P1 V1 = P2 V2

Substitute values of P1 V1 and P2

So, V2 = P1 V1 / P2 = 1 × 10.0/ 3.5 = 2.8957... Which is approximately equal to 2.9 cm^3

So the answer is 2.9 cm^3

Hope so you will get help with it
