Use the table below to answer questions 1 - 3.

Herman tested the effects of heat lost in an insulated cup of boiled water over time.
Below are the results of Herman’s investigation.

1 Which of the following correctly lists the number of trials that were conducted?

A. 3 trials
B. 5 trials
C. 8 trials
D. 10 trials

2 Which of the following would most likely be the results of the experiment if

Herman continued to measure the time it takes the water to reach 50ºC?

A. The heat lost in the insulated cup would be the same as the heat lost in
The non-insulated cup.

B. The heat lost in the insulated cup would be more than double that of the
non-insulated cup.

C. The heat lost in the insulated cup would be less than half that of the
non-insulated cup.

D. There would be no more heat lost from either cup.

3 Based on the data table above, which of the following do the results support?

A. “Insulated cups do not conserve heat”.
B. “Heat conservation can not be measured”.
C. “Non-insulated cups conserve heat just as well as insulated cups”.
D. “Insulated cups conserve heat”.
