Temperature is defined theoretically (it determines the direction of heat flow) and operationally (it's what a thermometer measures) and scales are compared.
On the Celsius and Fahrenheit scales, temperature is considered an interval variable, while on the Kelvin scale, it falls under the category of a ratio variable. Understanding the nuances of these scales helps us better analyze and interpret temperature data in scientific and everyday contexts.
Temperature is an important meteorological variable and it is used all over the world. What do you need to know about temperature?
The Boltzmann constant depends on how one defines one's unit temperature - in natural (Plank) units unity temperature is defined so that k = 1 k = 1. This definition hearkens back to Carnot's ingenious definition of temperature, whereby one chooses a "standard" heat reservoir and then measures the efficiency of an ideal heat engine working ...
We say that temperature and pressure are intensive variables, by which we mean that the temperature or pressure of an equilibrium system is independent of the size of the system and the same at any location within the system. Intensive variables stand in contrast to extensive variables.
Thermodynamic temperature is a physical state variable and is one of the seven basic variables in the International System of Units (SI) to which all metrological variables can be traced. Its unit of measurement is the Kelvin (K).
Temperature Variables mean daily temperature - average of the highest and lowest temperature for a 24 hour period annual range of temperature - the difference between the average temperature of the warmest and coldest months mean annual temperature - average of the twelve monthly average temperatures
The set of routinely collected measurements includes temperature, moisture, air pressure, wind direction, wind speed, cloud cover, visibility, precipitation and several other atmospheric variables. These observations form our understanding of how the atmosphere is "behaving" at any given moment and form the basis of weather forecasts.
Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).

The scientific definition of temperature is less ambiguous than your senses of hot and cold. Temperature is operationally defined to be what we measure with a thermometer. (Many physical quantities are defined solely in terms of how they are measured.
Temperature is an intensive variable as, for example, is the density of liquids. A quick test to decide whether a given variable is either extensive or intensive is to ask what happens to the number value if the amount of chemical substance in a system increases by a factor of two.
Temperature can be both an independent variable, where it is manipulated to observe its effect on other variables, or a dependent variable, where it is measured as an outcome of other factors.
Extensive variables: their value depends on the size of the system. For example: volume or mass, Intensive variables: their value is independent of the size of the system. For example: temperature, density, pressure. A simple way to figure out if a variable is intensive or extensive is to carry out the following thought experiment:
Temperature is defined theoretically (it determines the direction of heat flow) and operationally (it's what a thermometer measures) and scales are compared.
Explore Temperature, including its measurement, thermal equilibrium, absolute zero, and common temperature scales. Learn about heat vs. temperature, temperature conversions, and the significance of the Kelvin scale in scientific measurements.
Heat transfer is related to temperature change. Heat is equal to the product of the mass, the change in temperature, and a proportionality constant called the specific heat.
