A group of students were testing different insulators. They used three metal cans, one wrapped with bubble wrap, a second with a paper towel, and a third unwrapped. Equal amounts of hot water were poured into each can, and the temperature was noted at definite time intervals. The data is shown in the table.

Question

A new trial was performed by doubling the amount of paper towel around the can. What would the expected temperature be at 8 minutes for this new trial?
Responses
A 65
B 74
C 79
D 85

Answer 1

To determine the expected temperature at 8 minutes for the can wrapped with double the amount of paper towel, we would need to compare the results of the original trial with a single layer of paper towel to assess how the additional insulation impacts the temperature retention.

However, since the data from the original trial is missing, I can't directly analyze it to provide a precise expected temperature. Generally, more insulation (in this case, doubling the paper towel) would lead to less heat loss, resulting in a higher temperature than that of a can wrapped with a single layer of paper towel.

If we assume that the original trial with one layer of paper towel reached a specific temperature at 8 minutes, the new trial is expected to be higher than that due to the increased insulation effect.

If you have any actual temperature values or tendencies from the original trial, I could help estimate an expected temperature. If not, I would typically recommend selecting the higher temperature option from the provided choices.

Based on standard conclusions, the correct response might be B (74) or C (79), but this ultimately depends on the initial temperature data. Please provide any additional data available for better analysis.
