A sample of nitrogen gas has a volume of 450 cm3 and a pressure of 125 kPa. What volume would the gas occupy at 90 kPa if the temperature were to remain constant?

Answer 1

625 cm3

Explanation:

Formula V1 * P1 = V2 * P2

V1 = 450 cm3

P1 = 125 kPa

P2 = 90 kPa

V2 = ?

V2 = (V1 * P1) / P2

V2 = (450 cm3 * 125 kPa) / 90 kPa = 625 cm3
