Temperature Defined. Temperature is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.
Likewise, people ask, how does the temperature work?
When a substance gets hotter, it expands to a greater volume. Nearly all substances exhibit this behavior of thermal expansion. It is the basis of the design and operation of thermometers. As the temperature of the liquid in a thermometer increases, its volume increases.
Why is temperature measured in degrees Celsius?
The Celsius scale is known as a Universal System Unit. It is used throughout science and in most countries. At a temperature of Absolute Zero there is no motion and no heat. Absolute Zero occurs at 0 degrees Kelvin or -273.15 degrees Celsius or at -460 degrees Fahrenheit.
Why is the temperature so important?
Temperature is also important because of its influence on water chemistry. The rate of chemical reactions generally increases at higher temperature, which in turn affects biological activity. An important example of the effects of temperature on water chemistry is its impact on oxygen.
