Temperature is one of the most important factors affecting weather and all fields of natural sciences, as well as most aspects of daily life.
Temperatures vary with the time of day, which is why two terms are used to express that.
Namely: Great temperature, temperature Minor, and be maximum temperature of the highest temperature recorded in the day, the minimum temperature is less temperature registered on the same day.
The maximum temperature is measured by a thermometer or mercury meter, while the minimum temperature is measured using an thermometer or an alcohol meter. There are several units for measuring the temperature. The most famous of them are: Celsius, Fahrenheit, and Kelvin, and they were named according to the names of the scientists who created them, and the difference between them is based on determining the zero point, and the distance between the point and the next.
The scientific method for measuring temperature, which is subject to fixed standards, is to "measure the air temperature in the shadows", because measuring it in radiation will raise the temperature of the thermometer, which gives a temperature that does not match the temperature of the air.
And the thermometer is suspended in an open place to permanently renew the air, at a height of about one and a half to two meters from a dirt or grassy surface, because the metal surfaces retain heat, which affects the measurement of temperature and gives an irrational result.
