Question

( Answer the questions using the drop-down menus.

1. Which statement shows the direction of the transfer of heat in this experiment? The heat transfer is from the ( white paper, black paper, light bulb ) to the ( paper, light bulb ) .


2. Which statement compares the temperatures of the white and black sheets at 1, 2, and 3 minute(s)? The temperature ( is higher for the black paper, is higher for the white paper, is the same for both pieces of paper )

3. What conclusion can be made based on this data? ( the black paper absorb less heat. The white paper absorb less heat. The pieces of paper absorb the same amount of heat. ) ​

Answer 1

1. The heat is transferred from the light bulb to the paper.

2. The temperature is higher for the black paper.

3. The white paper absorb less heat.

Step-by-step explanation:

1. The heat is transferred from the light bulb to the paper.

This is because the light bulb is the source of heat in the experiment. Thus removing the light bulb implies that no heat would flow apart from the ambient heat.

2. The temperature is higher for the black paper.

A black body is a good absorber of heat. So, the temperature of the black paper would be higher compared to that of the white paper.

3. It can be concluded based on this data that: The white paper absorb less heat.

Since white surfaces are good reflectors of heat. Thus the white paper reflects most of the heat from the bulb, while absorbing very little fraction of it.
