Question

A sample of a gas has a volume of 639 cm3 when the pressure is 75.9 kPa. What is the volume of the gas when the pressure is increased to 125 kPa if the temperature remains constant? *

Answer 1

Answer:

0.388 L

Explanation:

We use the formula p1v1 = p2v2, since its saying temperature is constant.  You just simplify plug is what you know. Also convert cm3 to L, because thats the SI unit.

v1 = 639cm3 = 0.639L

p1 = 75.9kPa

v2=?

p2 = 125kPa

(0.639L)(75.9kPa) = (v2)(125kPa)

v2 = 0.388L
