A container contains 3.5 L of hydrogen gas at 32 degrees * C . What will be its volume if the temperature increases to 97 degrees * C keeping the pressure constant?

The answer to your question is  V2 = 4.2 l

Explanation:

Data

Volume 1 = V1 = 3.5 l

Temperature 1 = 32°C

Volume 2 = V2 = ?

Temperature 2 = T2 = 97°C

Process

1.- Convert temperature to °K

T1 = 32 + 273 = 305°K

T2 = 97 + 273 = 370°K

2.- Use Charles' law to solve this problem

                V1/T1 = V2/T2

-Solve for V2

                V2 = V1T2/ T1

3.- Substitution

                V2 = (3.5 x 370) / 305

4.- Simplification

                V2 = 1295/305

5.- Result

                V2 = 4.2 l
