Chapter 9, Problem 15TE

To determine

The reason behind the fact that the temperature of all objects do not continuously decrease even though they continuously emit radiant energy.

Answer to Problem 15TE

The temperature of all objects does not continuously decrease because they also continuously absorb energy from the surroundings which makes the temperature constant.

Explanation of Solution

The method of heat transfer through space is known as radiation. The energy transferred in this way is called radiant energy. The radiant energy is in the form of electromagnetic waves. It is transfer form one body to another without any medium.

Any substances at any temperature above absolute zero emit radiant energy. At the same time, they also absorb energy continuously from their surroundings. This intake of energy helps the substances from continuously decreasing its temperature.

Conclusion:

Therefore, the temperature of all objects does not continuously decrease because they also continuously absorb energy from the surroundings which makes the temperature constant.
