Question

An aerosol can contains gases under a pressure of 4.50 atm at 20.0 degrees Celsius. If the can is left on a hot, sandy beach, the pressure of the gases increases to 4.78 atm. What is the Celsius temperature on the beach? HINT: Temperature must be in Kelvin while solving the problem.

Answer 1

Answer: 40 degrees Celsius

Explanation:  

Equation to use: P1/T1   = P2/T2

First: add 273 K to 20 C to get 293        

Then plug the numbers into the equation: 4.50/293 = 4.78/x    

Then you want to cross multiply: 4.50x = 1400.54

Then solve for x:  x = 313 K

Then convert back to celsius: 313 – 273 = 40 C
