ElenaW [278]

Answer:

The answer to your question is 6.77 atm

Explanation:

Data

Pressure 1 = P1 = 7.5 atm

Temperature 1 = T1 = 65°C

Pressure 2 = P2 = ?

Temperature 2 = T2 = 32°C

Process

-Use Gay-Lussac law to solve this problem

               P1/T1 = P2/T2

-Solve for P2

               P2 = P1T2 / T1

-Convert temperature to °K

T1 = 65 + 273 = 338°K

T2 = 32 + 273 = 305°K

-Substitution

                P2 = (7.5 x 305) / 338

-Simplification

                P2 = 2287.5 / 338

-Result

                P2 = 6.77 atm
