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
