Answer:
The answer to your question is T2 = 146.52 °K
Explanation:
Data
Volume 1 = 2.85 L
Temperature 1 = 15°C
Temperature 2 = ?
Volume 2 = 1.45 L
Process
1.- Use Charles' law to solve this problem
V1/T1 = V2/T2
2.- Convert temperature to °K
T1 = 15 + 273 = 288°K
T2 = ?
3.- Substitution
2.85/288 = 1.45/T2
Solve for T2
T2 = 1.45(288)/2.85
Simplification
T2 = 417.6/2.85
Result
T2 = 146.52 °K
