Question

A sample of gas in a balloon has an initial temperature of 43 °C and a
volume of 1670 L . If the temperature changes to 94 °C, and there is
no change of pressure or amount of gas, what is the new volume, V2,
of the gas?
Express your answer with the appropriate units.

Answer 1

Answer:

V₂ = 3651 L

Explanation:

We can use Charles' Law here, as we change temperature and volume, but remain at a constant pressure:

V₁/T₁ = V₂/T₂ where V₁ and T₁ is our initial volume and initial temperature; V₂ and T₂ is our final volume and final temperature.

Let's plug in what we know and solve for the unknown:

1670 L / 43 °C = V₂ / 94 °C

V₂ = 3651 L
