Quick Answer: Is Calorimeter Constant Positive Or Negative?

What is a good calorimeter constant?

The “calorimeter constant” is just the specific heat of the calorimeter and its thermal conductivity.

An “ideal” calorimeter would have a very low specific heat and zero thermal conductivity because the point is to conserve energy within the system..

Is Ccal always positive?

Yes, heat capacity always has a positive value. It is the amount of energy (heat) required to raise the temperature of the system.

How do you use the calorimeter constant?

Subtract the energy gained by the cold water from the energy lost by the hot water. This will give you the amount of energy gained by the calorimeter. Divide the energy gained by the calorimeter by Tc (the temperature change of the cold water). This final answer is your calorimeter constant.

Can a calorimeter constant have a negative value?

The calorimeter constant can never be negative — if it is, you have made a mistake… Try performing multiple trials and averaging out the results of those trials to reduce your error. The uncertainty in your final average will be plus/minus 2x the standard deviation.

Why is the calorimeter constant important?

The calorimeter constants are used in constant pressure calorimetry to calculate the amount of heat required to achieve a certain raise in the temperature of the calorimeter’s contents.

Can a calorimeter constant have a negative value explain why or why not?

If the calorimeter constant is negative, it means that it will release heat when heated up, or absorb heat when cold. water is inserted, which is not logical.
