Question

Boyle's Law states that at a constant temperature, the volume of a gas is inversely proportional

to the pressure of the gas. (V:/V2 = P2/Pa). An unknown gas has an initial pressure of 150 kPa
and a volume of 1 L. If the volume is increased to 1.5 L, what will the pressure be now?

Answer 1

Answer: 100kPa at constant temperature.

Explanation:boyles law v1/v2 = p2/p1

v1 = 1L, p1 = 150 kPa, v2 = 1.5L

so p2 = p1*v1/v2 = 150*1/1.5 = 100 kPa
