Which instrument measures temperature?

Explanation:
To know how hot or cold the air is, you use a thermometer. It works by using a liquid (like mercury or alcohol) that expands or contracts with temperature, moving a scale to show the temperature. In weather stations, thermometers are protected in a shield to avoid direct sun and radiant heat so they read the true air temperature. The other instruments measure different things: a barometer gauges atmospheric pressure, which helps predict changes in weather; a rain gauge collects and measures rainfall; an anemometer measures wind speed. So the instrument that measures temperature is the thermometer.
