A sample of gas in a balloon has an initial temperature of 11 ∘C and a volume of 1.03×103 L . If the temperature changes to 70.
Andre45 [30]

Answer:

The answer to your question is  V2 = 1244 L

Explanation:

Data

Temperature 1 = 11°C

Volume = 1.03 x 10³ L

Temperature 2 = 70°C

Volume 2 = ?

To solve this problem use the Charles' law

        V1/ T1 = V2 / T2

-Solve for V2

        V2 = V1T2 / T1

Process

1.- Convert temperature to °K

Temperature 1 = 11°C + 273 = 284°K

Temperature 2 = 70°C + 273 = 343°K

2.- Substitution

         V2 = (1.03 x 10³)(343) / 284

3.- Simplification

        V2 = 353290 / 284

4.- Result

        V2 = 1244 L
