It is the dirrefernce between the highest and lowest temperature that is occurring over an area in a certain amount of time.
The definition of temperature range is the dirrefernce between the highest and lowest temperature that is occurring over an area in a certain amount of time.  : a measurement that indicates how hot or cold something is: a measurement in degrees showing the heat of something (such as air or water). : a measurement of the heat in a person's body. : a level of heat that is above what is normal for the human body.  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. An object's temperature is the best approximation of the kinetic energy of the particles. When we measure an object's temperature, we measure the average kinetic energy of the particles in the object. The higher the temperature, the faster the molecules of the substance move, on the average. As the temperature of the liquid in a thermometer increases, its volume increases. The liquid is enclosed in a tall, narrow glass (or plastic) column with a constant cross-sectional area. The increase in volume is thus due to a change in height of the liquid within the column. 1 The degree of hotness or coldness of a body or environment. 2  A measure of the warmth or coldness of an object or substance with reference to some standard value. 3  A measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale. Temperature. People usually describe the temperature as hot or cold. The real definition of temperature is the measure of the average speed of air molecules. Temperature is measured in degrees by using a thermometer. They are rea d in the shade because their measurements are too high when placed in direct sunlight The wind chill index is the temperature your body feels when the air temperature is combined with the wind speed. The higher the wind speed the faster exposed areas of your body lose heat and the cooler you feel. Click Here to look at the wind chill index conversion chart or use the wind chill calculator below.  Heat and temperature are related, but not the same. Temperature is a measure of the average kinetic energy of the particles of a substance. The higher the temperature of an object, the higher is its kinetic energy. Kinetic energy is a type of energy associated with motion. Temperature is measured with thermometers, which are devices that use the expansion of a substance to give an indirect measure of temperature. An object's temperature is the best approximation of the kinetic energy of the particles. When we measure an object's temperature, we measure the average kinetic energy of the particles in the object. The higher the temperature, the faster the molecules of the substance move, on the average. The relative humidity of an air-water mixture is defined as the ratio of the partial pressure of water vapor in the mixture to the equilibrium vapor pressure of water at a given temperature: Relative humidity is normally expressed as a percentage; a higher percentage means that the air-water mixture is more humid.
