Question

If you have a gas at a constant temperature, a pressure of 1.2atm and a volume of 25mL, what will be the pressure if you increase the volume to 44.6mL?

Answer 1

answer and explanation

the question can be solved using Boyle's law which states

P1V1 = P2V2

P1 = 1.2 atm

V1 = 25 mL

V2 = 44.6 mL

P2 = ?

solution

rearrange the formula to make P2 the subject of the equation as follows:

P2 = P1V1/V2

= (1.2 x 25)/44.6

= 0.67 atm

the pressure will be 0.67 atm
