Gas Law Problem #1

Question

The gases in a hair spray can are at a temperature of 27 degrees Celsius and a pressure of 30 psi. If the gases in the can reach a pressure of 90 psi, the can will explode. To what temperature must the gases be raised in order for the can to explode? - Show Work.

 

Temperature and Pressure are changing so I'm guessing it's Gay-Lussac's Law so probably using that equation might help, I'm not wrong...

Answer 1

Yes, you want to use Gay Lussac's law.  P1/T1=P2/T2  Make sure you change your temperature values to Kelvin.  Add 273 to your Celsius values to do that.  

 

30 psi/300 K = 90 psi/T2  

 

Find T2

 

T2-273 gives you the correct temperature in Celsius
