Initial Temp Homework: Copper in Water, Aluminum Cup

In summary, the Initial Temp Homework is an experiment that involves placing a piece of copper in water in an aluminum cup to observe the change in temperature over time. The materials needed include copper, water, an aluminum cup, a thermometer, and a timer. The expected outcome is a decrease in the water temperature as the copper absorbs heat. This experiment is significant as it demonstrates thermal equilibrium and allows for the calculation of specific heat capacities.

Homework Statement


A student doing an experiment pours 0.150 kg of heated copper **** into a 0.375 kg aluminum calorimeter cup containing 0.200 kg of water. The cup and water are both initially at 25 C. The mixture (and the cup) comes to thermal equilibrium at 28 C. What was the initial temperature of the shot?


Homework Equations


The only equations in the chapter are specific heat:

Q=cm(delta)T or c=Q/m(delta)T

1. What is the purpose of the Initial Temp Homework?

The purpose of the Initial Temp Homework is to determine the change in temperature when a piece of copper is placed in water in an aluminum cup.

2. What materials are needed for the Initial Temp Homework?

The materials needed for the Initial Temp Homework include a piece of copper, water, an aluminum cup, a thermometer, and a timer.

3. How is the experiment set up for the Initial Temp Homework?

The experiment is set up by filling the aluminum cup with a known amount of water and recording its initial temperature. Then, the copper is placed in the water and the temperature is recorded every minute for 10 minutes.

4. What is the expected outcome of the Initial Temp Homework?

The expected outcome of the Initial Temp Homework is to see a decrease in the temperature of the water as the copper absorbs heat from the water.

5. What is the significance of the Initial Temp Homework?

The Initial Temp Homework is significant because it demonstrates the concept of thermal equilibrium and how heat is transferred between objects of different temperatures. It also allows for the calculation of specific heat capacity of copper and the heat capacity of water.
