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

Nonamiya [84]

Lets do process of elimination!

A. Breaking glass - That is a psychical change because if you break it, it is still glass. It didn't change to another substance.

B. Melting ice on a windshield - During the melting process, there is no chemical change, and therefore, no new substance is created.  

C. Burning gasoline - When gas burns it usually combines with oxygen to give carbon dioxide, water etc.  It is a chemical change.

D. Denting a bumper - The bumper is still a bumper, only thing is it has a dent in it. The properties did not change, meaning no chemical change.
