Chapter 16: Problem 4

If you put a thermometer in direct sunlight, what do you measure: the air temperature, the temperature of the Sun, or some other temperature?

Short Answer

Expert verified

A thermometer in direct sunlight measures a combination of the air temperature and the added temperature from the absorbed solar radiation, not the temperature of the Sun.

Step by step solution

Understand how a thermometer works

A thermometer is a device that measures temperature or temperature gradient. It works by detecting changes in its physical properties due to temperature variations. Its purpose is to take readings of the surrounding environment's temperature.

Evaluate the influence of direct sunlight

When placed in direct sunlight, a thermometer is exposed not only to the ambient air temperature but also to the warmer temperatures generated by the absorbed solar radiation.

Conclude what the thermometer measures

By all accounts, a thermometer in direct sunlight measures a combination of the air temperature and the temperature resulting from the absorbed solar radiation, rather than the temperature of the Sun. It's important to note that the temperature reading is likely to be higher than the actual air temperature due to the heat absorption of the exposed surfaces.
