Question

A gas occupies a volume of 100 mL at pressure of 200 kPa. Find its volume at a pressure of 300 KPa.

Answer 1

67 mL

Step-by-step explanation:

Ideal gas law:

PV = nRT

If number of moles (n) and temperature (T) are constant, then:

PV = constant

Therefore:

P₁V₁ = P₂V₂

(200 kPa) (100 mL) = (300 kPa) V

V ≈ 67 mL
