Question

A gas at 61◦C occupies 4.75 L. At what temperature will the volume be 3.17 L, assuming

the same pressure?

Answer in units of ◦C.

Answer 1

Constant pressure (Charles's law)

V₁/T₁ = V₂/T₂

T₁/V₁ = T₂/V₂

T₂ = T₁V₂/V₁

T₂ = (273.16+61)(3.17) / (4.75) = _____ K

subtract 273.16 to get ºC
