Charles's law — volume and temperature

A gas at 27 °C occupies 3.00 L. At constant pressure, calculate the volume at 127 °C (Charles: V₁/T₁ = V₂/T₂, T in Kelvin).

Given data

T₁ = 27 °C = 300 KV₁ = 3.00 LT₂ = 127 °C = 400 K

Steps

0 / 1

Calculate V₂ = V₁ × T₂/T₁.
Write your working — the numerical result must appear in the text L

Full worked solution

Calculate V₂ = V₁ × T₂/T₁.
$3.00 \cdot \frac{400}{300}$
$3.00 \cdot \frac{400}{300} = 3.00\times400/300 = 4.00 = \mathbf{4.00\,L}$ . Volume increases with temperature by Charles's law.

Result:V₂ = 4.00 L.
