Question

4. Suppose you have a sample of CO2 in gas-tight syringe. The gas volume is 25.0 mL at 20.0°C. What is the final volume of the gas if you hold the syringe in your hand to raise the temperature to 37°C? (26.5 mL)

Answer 1

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

V₁ = 25 mL , T₁ = 20⁰C , V₂ = ? , T₂ = 37⁰C

$\frac{25mL}{20⁰C} = \frac{V_2}{37⁰C}$

V₂ = 46.25 mL is the final volume
