Hydrogen gas occupies a volume of 400cm3 at a temperature of 300k normal atmospheric pressure.Find the volume of gas at 283K at constant pressure.

Solution

According to Charle's Law : For a fixed mass of gas at constant pressure (P) ,the volume is directly proportional to the kelvin temperature (T).
V ∝ T
Or, T₁ /T₂ = V₁ /V₂
V₁ = 400 cm³
T₁ = 300 K
V₂= ?
T₂ = 283 K

V₂= V₁ /T₁ xT₂
= 400 cm³/ 300 K x 283 K
= 377 cm³
