The table shows the same data about how the temperature of each pizza changed over 15minutes.

Pizza Initial temperature (°C) Final temperature (°C)
Pizza on the bottom 85 68
Pizza on the top 85 61
Which statement is correct?

which statement is correct?
thermal energy was transferred more slowly out of the pizza on the bottom
thermal energy with transfer more slowly out of the pizza on the top
thermal energy was transferred out of both cases at the same time

1 answer

The correct statement is: thermal energy was transferred more slowly out of the pizza on the bottom.

This is because the pizza on the bottom had a higher final temperature (68°C) compared to the pizza on the top (61°C). A higher final temperature indicates that it retained more thermal energy, which suggests that thermal energy was lost more slowly in the pizza on the bottom than in the pizza on the top.
