Lab: Energy Transfer

Question 1

Which method transfers heat from the Sun to the ocean?

Revolt · Accepted Answer

radiation; convection; conduction

Question 2

What did you include in your response? Check all that apply.

Revolt · Accepted Answer

The melting of the pieces of chocolate one by one is evidence that conduction occurred.; As heat flowed through the foil bridge, heat transferred to the pieces of chocolate, causing them to melt.; The heat transfer occurred between the foil bridge and the chocolate pieces, which were in direct contact with one another.

Question 3

Revolt · Accepted Answer

✔ warmer than

Question 4

The black paper absorbs less heat.✔ The white paper absorbs less heat.The pieces of papers absorb the same amount of heat.

Revolt · Accepted Answer

✔ The white paper absorbs less heat.

Question 5

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.

Revolt · Accepted Answer

✔ Conduction; 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.: Conduction; 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.: convection; In this lab, you modeled and observed the three main ways thermal energy is transferred.

Question 8

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

Evidence that conduction occurred is seen when the chocolate pieces melt one after the other starting from the end closest to the heat source. Heat energy moved through the aluminum foil bridge, and since the chocolate pieces were in direct contact with the foil, heat was transferred to them through conduction.

Question 9

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

Revolt · Accepted Answer

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

Question 10

Complete the sentences to describe the convection experiment.

Revolt · Accepted Answer

✔ red water in hot water; 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.: red water in hot water; 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.: rose to the top of the beaker; 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.: warmer than
