Question

Terrance designed an experiment to show how heat can be transferred from one place to another. The steps of the experiment are shown below.
1. Place a lamp light on a table.
2. Place palm about 6 inches below the lamp light.
3. Feel the heat from the lamp light on the palm.

What does Terrance's experiment most likely demonstrate?
A. heat transfer by radiation
B. heat transfer by evaporation
C. energy transfer by melting
D. energy transfer by conduction

Answer 1

I think its a) heat transfer by radiation

Answer 2

Answer:

Option (A)

Explanation:

There are three modes of transfer of heat.

1. conduction

2. Convection

3. radiation

Radiation is the process in which the heat travels through the medium without being heated the interventing medium. In this mode of heat transfer there is no requirement of medium.

So, here, the palm is heated due to the heat transfer from the lamp by the mode of radiation.
