The gas in a balloon has a volume of 2 Lat a temperature of 301 K. What will be the final temperature (in K) when the volume exp
Blizzard [7]

Answer:

Final temperature = 1279.25 K

Explanation:

We can solve this using the formula for Charles law since we are given volume and temperature.

From Charles law, we know that;

V1/T1 = V2/T2

Where;

T1 is the initial temperature

V1 is the initial volume

T2 is the final temperature

V2 is the final volume

We are given;

V1 = 2 L

T1 = 301 K

V2 = 8.5 L

Thus, making T2 the subject, we have;

T2 = V2•T1/V1

Plugging in the relevant values;

T2 = 8.5 × 301/2

T2 = 1279.25 K
