The pressure of the gas is 112 kPa when its temperature is 35 °C.
The gas is heated to 340°C using some different apparatus.
Calculate the pressure of the gas when its temperature is 340 °C.
Assume the gas has a constant volume.
Pressure =
kPa

Answer: Pressure = 223 kPaExplanation:Given:p₁ = 112 kPa = 112 000 Pat₁ = 35°C;    T₁ = 273 + 35 = 308 Pat₂ = 340°C;    T₂ = 273 + 35 = 613 PaV - const___________p₂ - ?Charles' law:p₁ / T₁ = p₂ / T₂The pressure:p₂ = p₁·T₂ / T₁p₂ = 112 000·613 / 308 ≈ 223 000 Pa   or  p₂ = 223 kPa
