Question

What conclusion could you make about conduction and convection based on these observations?

Answer 1

Answer:

The Answer is B.)Convection is a more efficient method of heat transfer.

Explanation:

In fluids, such as water and air, convection is a much more efficient method of heat transfer than conduction.  Although conduction was at work in both cases, it transferred much less heat than convection.

Answer 2

C) No valid conclusion is suggested by these observations.

Explanation:

From the experiment, no valid conclusion can be drawn from the observations.

The tests are simply based on heat loss by a material.

• In conduction, heat is lost by contact between materials in which heat flows from one to another.
• Convection is a form of heat loss in which heat flows by density in fluids
• The test carried out does not provide proof and comparison between heat loss by conduction and convection.
