(About Ads) On a video chad said that temperature is directly proportional to Energy through another formula that's not important to memorize. My question is that does the temperature have to be in Celsius or Kelvin? because a change from 1 Celsius to 2 Celsius is not considered doubled if temp was suppose to be in Kelvin ( 273 to 275)

The only time when it would be ok to use Celsius is when you're talking about temp differences and you're calculating Tf-Ti.

Yea, the only thing keeping me going is knowing (hoping) that in a year I'll be able to quit and start med school!

 06-17-2012, 10:33 PM #7 Hello there     Status: Pre-Medical Join Date: Aug 2010 Posts: 178 I believe the formula you're referring to is Q=mc(tf-ti) Q= heat energy M= mass C= heat capactiy tf-ti= change in temperature In this case whether you use celsius or kelvin doesn't matter, 1 degree celsius change = 1 degree kelvin change. But still, use kelvin when in doubt, because it's SI
