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
