***Determining specific heat through insulating through coffee cup. Aluminum is heated and then immediately put in a thermal cup containing water.. Shaked.. then Final Temperature is determined.

4. What does this experiment show about the specific heat of water?

5. How does the conductivity of the metal used in this experiment affect the accuracy of the results?

Homework Answers

Answer #1

Answer:

(4) From the given experiment, the two substances exchange their heat energy with each other so that the amount of heat lost by the hotter substance is gained by the colder substance until they reach thermal equilibrium. The amount of heat absorbed by the colder water would then be equal with the amount of heat lost by the heated metal. Therefore, it was proven that water absorbs more heat than the thermal cup since it has a higher specific heat.

(5) The thermal (heat) conductivity may changes the accuracy of the results obtained. The rate of thermal conductivity can be affected by the materal properties of the given metal, such as specific heat, thickness, surface area and its original material's nature.
