Hey!
That's a great question; let's look into it.
The calorimetry formula is used to measure the transfer of heat in a closed system.
Therefore, when the temperature variation (△t) is negative, the reaction releases heat. On the other hand, when the temperature variation is positive, the reaction absorbs heat.
I hope that helps! If you have other questions, you know where to find us!
