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.

have a good day!

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
