WHAT IS TEMPERATURE?
You observed that sometimes the air gets warm and at other times, it
gets cold. The degree of hotness and coldness of air is called temperature.
Temperature Changes During The Day
An area gets hotter when it is heated by the sun and gets cool when the
heat leaves the area. The coldest time of the 24-hour day is just before sunrise,
after the Earth has been losing heat all night.
Air temperature is measured by a device called air thermometer. It is
expressed in degree Celsius or . A thermometer is a narrow glass tube
containing mercury or colored alcohol. As the temperature increases, the mercury
or alcohol expands and its level in the tube rises. The number corresponding to
the liquids level is the temperature reading.
Air temperature affects the weather conditions. During warm weather, the
temperature rises. We say the temperature is high. During cooler days, the
temperature sinks or drops. We say the temperature is low. The average air
temperature is 19-32 . A temperature reading below 19 means it is cold. A
temperature reading above 32 means it is warm.
Air temperature changes from time to and from place to place.
