Question

A sample of gas in a closed flexible container has a starting pressure of 112.1 kPa and volume of 5.1 L. If the temperature goes from 300.0 K to 339.5 K, what is the new pressure in kilopascals if the new volume is 9.8 L?

Answer 1

From ideal gas law, P₂V₂ /P₁V₁ = T₂ /T₁, P₂ = P₁V₁T₂ /V₂T₁ = (112.1)(5.1)(339.5) /[(9.8)(300)] = 66.0 kPa
