Question

A diver observes a bubble of air rising from the bottom of a lake, where the pressure is 4.00 atm, to the surface, where the pressure is 1.00 atm. The temperature at the bottom of the lake is 5.0°C, and the temperature at the surface is 29.0°C. What is the ratio of the volume of the bubble as it reaches the surface to its volume at the bottom? You may use p1V1/T1 = p2V2/T2

I know how to derive the answer....my question is do we change the degrees celcius to kelvin every time we deal with problems using the ideal gas law. There is a similar problem with Jacques the diver that uses an absolute pressure at the bottom of the lake and they change the celcius to kelvin which gives a totally different answer to the problem.

Explanation / Answer

Yes b/c gas constant is in J/mol K

Hope this helped!
