Is change in temp for calorimeter inverted?

Postby Andie Jian 1D » Sun Feb 10, 2019 4:53 pm

I understand that q=-qCal, implying that C(deltaT) = -Ccal(deltaT). However, for the side for the calorimeter, would we have to switch T1 and T2 because the heat released by the system is opposite the heat gained by the calorimeter? Or is it different because a change in temperature is different than a change in heat? I'm a bit confused!

Delta T will state the same so don't switch it! The change in temperature remains the same and the sign is accounted for by the negative already at the front of the equation, also temp changes are different from heat changes, temperature is a state function while heat is energy and depends on how you get that amount of energy. Hope this helps!
