help lemon get 5 extra points on her first chem test!

my chemistry teacher will give us 5 extra points on the test if we can find out the name of this law:

 

that the specific heat capacity of every metal is ~0.8g/degrees C

 

i thought he was messing with us but someone actually managed to find it today. i've looked online and i can't quite seem to find it. anyone that's awesome at searching for crap on the internet want to try to give me a hand? he also said today that it might be less of a "law" and more of a "rule of thumb." any help appreciated.

Look up Dulong–Petit law and let me know if thats even close lol I suck at this game

Hey! I just said the same thing in the Vind forums. Maybe we're on the right track!

yea i found something similar

seems like dulong-petit might be it, "This relationship is only approximate, but it has become a useful rule of thumb. The so-called “law” of Dulong and Petit"

i ran across that and wondered if it was what i was looking for, so it's good to have some confirmation from THE INTERNET AT LARGE that it might be. thanks guys ^^

Hey Lemon did we ever find out if thsi was right?

If it is correct, I take full credit. If it's not correct, clearly it's Myrevenge's fault.

he said it was "close enough to be right" but didn't bother explaining like... why. but who cares! 5 points for me
