What is the pressure of a fixed volume of hydrogen gas at 32.9°C if it has a pressure of 1.39 atm at 15.0°C?

Question

What is the pressure of a fixed volume of hydrogen gas at 32.9°C if it has a pressure of 1.39 atm at 15.0°C?

Answer 1

We will be using Charles law because we are only given the Pressures and Temperatures. Also, note in the question it says the volume is fixed.

P₁ = ? P₂ = 1.39 atm

T₁ = 32.9 C + 273 = 305.9 K T₂ = 15.) C +273 = 288 K

Charles Law is as follows:

P₁/T₁ = P₂/T₂

P₁ = 1.39 atm( 305.9 K) = 1.48 atm

288 K
