Question

A gas gas a volume of 4.0 liters at a pressure of 0.80 atm. What is the volume if the pressure is changed to 0.40 atm at a constant temp

Answer 1

The volume is 8,0 L.

Step-by-step explanation:

We apply Boyle Mariotte's Law: for a given mass of gas at constant temperature, its pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa):

P1 x V1 = P2 xV2

V2 = (P1 x V1)/P2

V2 = ( 0,80 atm x 4,0 L)/ 0,40 atm

V2= 8,0 L
