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.

In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 19.5 grams of tungsten to 97.80°C and then drops it into a cup containing 78.3 grams of water at 22.58°C. She measures the final temperature to be 23.20°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of tungsten to be  J/g°C.

two parts for one question ----------------------------------------- In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter and the value determined is called the calorimeter constant. One way to do this is...
