​We're going to walk through how to answer questions 1-9 by using this sample data

Multiple Choice

Question 2: What was the final temperature of the metal after it was placed in the water in the calorimeter? How do you know?

• 99.5⁰C

• 23.4⁰C

• 31.6⁰C

• 67.9⁰C

STOP!

Multiple Choice

Question #3: Calculate the change in temperature of the metal sample.

• ΔT = -67.9⁰C

• ΔT = -76.1⁰C

• ΔT = 67.9⁰C

• ΔT = 99.5⁰C

STOP!
Check that your answer for number 3 is correct according to your data. Make any necessary corrections before moving on.

Multiple Choice

Question #4: Did the water in the calorimeter gain or lose energy when the metal was placed in it? How do you know?

• The water lost energy when the metal was placed in it. I know this because the temperature of the water decreased.

• The water gained energy when the metal was placed in it. I know this because the temperature of the water increased.

• The water gained energy when the metal was placed in it. I know this because the water gave the metal thermal energy.

• The water neither gained nor lost energy. I know this because the temperature did not change.

STOP!
Check that your answer for number 4 is correct according to your data. Make any necessary corrections before moving on.

Multiple Choice

Question #5: Did the metal sample gain or lose energy when it was placed in the water in the calorimeter? How do you know?

• The metal sample lost energy. I know this because it looked different.

• The metal sample neither gained nor lost energy. I know this because the temperature remained the same.

• The metal sample gained energy. I know this because the temperature increased.

• The metal sample lost energy. I know this because the temperature decreased.

STOP!
Check that your answer for number 5 is correct according to your data. Make any necessary corrections before moving on.

STOP!
Check that your answer for number 6 is correct according to your data. Make any necessary corrections before moving on.

Multiple Choice

Question #7: What is the amount of energy, in joules, lost by the metal sample? Explain how you know.

• 1,371.04J

• -1,371.04J

• 25.0g

• 31.6⁰C

STOP!
