If the result after calculating the heat of the calorimeter is negative, what conclusion can you make?

It means that the signs of the temperatures are calculated wrong

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.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
