    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!
