What device measures heat energy and provides a temperature reading?

Explanation:
Measuring heat energy and obtaining a temperature reading is done with a thermometer. Traditional thermometers use a liquid that expands when heated, so as temperature rises the liquid level climbs and can be read on a scale. Digital thermometers use electronic sensors to measure temperature and display the value numerically. This differs from a barometer, which gauges atmospheric pressure; a hygrometer, which measures humidity; and anemometers, which measure wind speed. Since only a thermometer directly measures heat energy and gives a temperature reading, it is the correct device.
