Question

A student is investigating the transfer of thermal energy. She creates a diagram to show the particles of two substances with different amounts of thermal energy.



The student must create a diagram of the two substances when they are touching each other. Which describes the diagram she should draw?

a
The student should draw energy transferring through conduction from B to A, because B has more thermal energy.
b
The student should draw energy transferring through conduction from A to B, because A has more thermal energy.
c
The student should draw energy transferring through convection from B to A, because B has less thermal energy.
d
The student should draw energy transferring through convection from A to B, because A has less thermal energy.

Answer 1

The correct answer is:

**a**
The student should draw energy transferring through conduction from B to A, because B has more thermal energy.

This choice accurately describes the process of heat transfer (conduction) occurring from the substance with higher thermal energy (B) to the substance with lower thermal energy (A) when they are in contact.
