Patti used a steel wrench to work on her bicycle on a hot, sunny day. she left the wrench on the hot concrete surface for an hour while she had lunch. when she returned, the wrench was very hot to touch. what is the best explanation for how the wrench got so hot? a. heat transferred from the wrench to the air. b. heat transferred from the wrench to the concrete. c. heat transferred from the concrete to the wrench. d. heat transferred from the bicycle to the wrench.

Option (C) is the correct answer.

Explanation:

It is given that concrete was hot and Patti left the wrench on hot concrete surface while she had lunch.

This means that heat has been transferred from the concrete to the wrench as a result, the wrench has become very hot to touch.

Thus, we can conclude that heat transferred from the concrete to the wrench is the best explanation for how the wrench got so hot.

The correct option is Option C.

Explanation:

When Patti left the wrench on hot concrete surface for an hour while having lunch, heat got transferred from hot concrete surface to the wrench by the process of conduction.

Conduction is one of the mode of heat transfer. It occurs when heat is transferred from a surface of high temperature to a surface of low temperature whenever two surfaces are in direct contact with each other.

Hence, the correct answer is Option C.
