Thank you very much for your help.

Thanks for your reply. Maybe it can be related with whether it is celsius or centigrade but it sounds strange when it is heard as they are not equal each other. Is there anyone who have strange or different opinion? Or, i mean, what will I write in my homework :)

Sorry for misunderstanding. Instructor wrote on the blackboard as this: Is 1K (Kelvin) difference equal or not equal to 1C (celsius) difference? Everybody said that yes they are equal to each other but our instructor said that no they are not equal to each other and wanted from us to prove...

Homework Statement All we know think that 1C = 1K as difference. But our instructor said that they were not equal each other and wanted from us that we would prove this as homework. How can we prove that they were not equal each other? Homework Equations The Attempt at a Solution

Hi to Everyone. I need also "derivation of energy equation in spherical coordinates" but i also could'nt find anything. Is there any information about this by explaining how to derive the equation by term by term?
