Answer:
It means that the signs of the temperatures are calculated wrong
Explanation:
When the mass of substance is multiplied with the specific heat, the product is equal to heat capacity, which is donated as \(C\) and can be seen on the calorimeter. Heat capacity, C, can never be negative for a mass or a substance and the specific heat of a substance can never be negative. So if it is negative it means that the calculations went wrong.
