In the introduction of this activity, we mentioned the temperature of your home on hot and cold days. Your body is kept warm in your home primarily by two ways: by direct contact with the air around you and by absorbing infrared light that is radiated from the walls. As you have seen in this activity, the light that is radiated from an object depends almost solely on the temperature of the object. Based on what you have learned here, what is one reason for feeling warmer in your house on a summer day versus a winter day even though your thermostat is set the same?

a - The walls of the house are warmer during the summer. Therefore, they radiate more infrared light that can serve to warm our body.
b - The walls of the house are warmer during the summer. Therefore, they radiate more visible light that can serve to warm our body.
c - The walls of the house are warmer during the summer. Therefore, they radiate more ultraviolet (UV) light that can serve to warm our body.
d - The temperature of the walls of the house has no effect on the light they radiate.

The answer is Option(a). According to studies, the reason to feel warmer inside the house is the absorption of infrared radiations emitted by the walls. Also more the temperature of the body, the more the heat radiated by it. During summer the walls of the house are at higher temperature for which they emit more infrared radiations which our body absorbs and make us feel more warmer.

Answer:

a) The walls of the house are warmer during the summer. Therefore, they radiate more infrared light that can serve to warm our body.

Explanation:

Option a) is the correct one, since to feel a little warmer being inside the house has to do with absorbing the infrared radiation that is transmitted by the walls. It is well known that in the summer the walls of a house tend to heat up to a higher temperature, therefore they are capable of emitting the infrared radiation that the body of anyone inside a house is capable of absorbing and causing those people feel warmer.
