Lab: Energy Transfer

Question 1

Throughout the reflection, make sure that you have the copy of the student guide, PDF or Word and your data tables. Complete the paragraph by using the drop-down menus. In this lab, you modeled and observed the three main ways thermal energy is transferred. When thermal energy transfers from a warmer body or place to a cooler body or place, it is referred to as heat. involves the transfer of heat between two bodies that are touching, is the transfer of heat in a liquid or gas, and is the transfer of heat through space.

C: Conduction

Question 2

What evidence from the experiment shows that conduction occurred? In your answer, be sure to include the materials involved in the transfer of heat through conduction.

Revolt · Accepted Answer

The melting of the chocolate pieces one by one showed that it was caused by heat flowing through the foil bridge. The transfer of heat happened between the foil bridge and the chocolate pieces because they were touching each other.

Question 3

Which statements describe how heat flows in foil? Check all that apply.

Revolt · Accepted Answer

A: Heat flows in all directions.; D: The atoms near the candle absorb heat first.; F: Heat flows from the warmer atoms to the cooler atoms.

Question 4

Complete the sentences to describe the convection experiment. The model showed convection. In the convection model, the red water on the bottom of the beaker . This means that the water at the bottom of the beaker was the water near the top of the beaker.
