It is OK to use your textbook, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.

In this experiment we will collect data that will allow the determination of the specific heat of aluminum metal. Look at the questions below and then watch the video. When you have the information required to complete a question, pause the video by pressing the spacebar, and record the data. Pressing the spacebar again will re-start the video.

1. Enter the mass of the aluminum cylinder as measured using the analytical balance.

grams

2. Enter the mass of the water in the coffee-cup calorimeter as measured using the analytical balance.

grams

3. Enter the initial temperature of the water in the coffee-cup calorimeter;

°C

4. Enter the initial the temperature of the aluminum;

°C

5. Enter the final temperature of the water in the coffee-cup calorimeter;

°C

6. Enter the final temperature of the aluminum in the coffee-cup calorimeter;

°C

7. Calculate the specific heat for the sample aluminum used in this experiment.

joules/g-1 °C-1

8. Using your textbook or an online resource determine the literature value of the specific heat of aluminum in joules/g-1 °C-1.

joules/g-1 °C-1

9. Speculate why the specific heat for aluminum that you determined from the experiment does not agree with the literature value of the specific heat.

10. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

11. If there is one question you would like to have answered in lecture, what would that question be?
