Question

Calculate the temperature to which a .400 L sample of gas at 1.00 atm and 0 degrees celcius must be heated at a constant pressure for the volume to change to 1.00L

Answer 1

If P = const we can use Charles's law. Due to it we have
V₁/T₁ = V₂/T₂
From this equation we get that
T₂ = (T₁*V₂)/V₁ = (273 K*1 L)/4 L = 68.25K = -204.75 degrees celsius.
