A balloon is filled at 1 atm with gas that occupies 2.3 dm³ in a laboratory at 19 °C. The balloon is then taken from this laboratory to a tropical greenhouse at 1 atm where the temperature is 38 °C. What is the resulting volume (dm³) of the balloon?

Using Charles's Law (V1/T1 = V2/T2), where V1 = 2.3 dm³, T1 = 19°C (292 K), T2 = 38°C (311 K), we find V2 = (2.3 dm³ * 311 K) / 292 K = 2.45 dm³.
