Temperature units for Entropy

Postby siannehazel1B » Mon Jan 29, 2018 10:15 am

When solving for entropy when there is a change in temperature while Volume is constant, does it matter if we calculate the T2/T1 in Kelvin or Celcius? If so, which one are we expected to be using?

It does make a difference since the temperatures are being divided you would get different answers for Kelvins vs Celsius. I think you should be using Kelvins but Im not sure why. might be in the derivation of the formula!

It matters, since calculating in Kelvin versus in Celsius gives you different values for the natural log. Entropy should be calculated using Kelvin.
