Which statement is correct?

A) Thermal energy (heat) was transferred faster out of the pizza on the bottom.
B) Thermal energy (heat) was transferred faster out of the pizza on the top.
C) Thermal energy (heat) was transferred out of both pizzas at the same rate.

Answer 1

B) Thermal energy (heat) was transferred faster out of the pizza on the top.
This is because the top of the pizza is closer to the atmosphere and collide with air particles making it cold when left a certain duration.
