Question

Combined gas law, A gas balloon has a volume of 106L when the temperature is 318K and the pressure is 1.5 atm. What will its volume be at 293 K and 2 atm.

Answer 1

P1 x v1/t1 = p2 x v2 / t2

use the given values:

1.5 x 106 / 318 = 2 x v2 / 293

Simplify:

0.5 = (2 x v2)/293

Multiply both sides by 293:

146.5 = 2 x v2

Divide both sides by 2:

V2 = 73.25 L

Answer: 73.25 L
