Question

A gas sample contained in a cylinder equipped with a moveable piston occupied 300 mL is a pressure of 2 atm. What would the final pressure if the volume were increased to 500 mL at constant temperature

Answer 1

1.2 atm

Step-by-step explanation:

This uses only two variables V and P, meaning that we can use Boyle's Law which is
`{V_(1) }{P_(1)} = {V_(2)}{P_(2)}`

Given V1= 300 mL , P1= 2 atm, V2= 500 mL,

300 * 2 = 500 * P2

P2 = 600/500

P2 = 1.2 atm
