A sealed cylinder of gas contains nitrogen gas at 104 kPa pressure and a temperature of 24 ºC. When the cylinder is left in the sun, the temperature of the gas increases to 54 ºC. What is the new pressure of the gas in kPa?

P₁ = 104 kPa, T₁ = (273 + 24) K = 297 K
P₂ = ? kPa, T₂ = (273 + 54) K = 327 K
P₁/T₁ = P₂/T₂
104/297 = P₂/327
New pressure, P₂ = (104/297) × 327 kPa = 114.5 kPa
P₂ = ? kPa, T₂ = (273 + 54) K = 327 K
P₁/T₁ = P₂/T₂
104/297 = P₂/327
New pressure, P₂ = (104/297) × 327 kPa = 114.5 kPa
