Temperature determines the statistical occupation of the microstates of the ensemble. The microscopic definition of temperature is only meaningful in the thermodynamic limit, meaning for large ensembles of states or particles, to fulfill the requirements of the statistical model. Kinetic energy is also considered as a component of thermal energy.
The most important thermophysical property is thermal inertia, which controls the amplitude of the thermal curve and albedo (or reflectivity), which controls the average temperature. This field of observations and computer modeling was first applied to Mars due to the ideal atmospheric pressure for characterising granular materials based upon ...
Thermal physics, generally speaking, is the study of the statistical nature of physical systems from an energetic perspective. Starting with the basics of heat and temperature, thermal physics analyzes the first law of thermodynamics and second law of thermodynamics from the statistical perspective, in terms of the number of microstates corresponding to a given macrostate.
Most biological processes are dependent upon enzymatic activity that can be impacted by the organism's body temperature, which in term is a function of the organism's metabolism and environment as each enzyme has a finite window in which it can function properly. An organism's niche in the environment may then be dependent upon the thermal ...
A temperature gradient is a physical quantity that describes in which direction and at what rate the temperature changes the most rapidly around a particular location. The temperature spatial gradient is a vector quantity with dimension of temperature difference per unit length. The SI unit is kelvin per meter (K/m).
Biogeography (an amalgamation of biology and geography) is the comparative study of the geographic distribution of organisms and the corresponding evolution of their traits in space and time. [146] The Journal of Biogeography was established in 1974. [147] Biogeography and ecology share many of their disciplinary roots.
The variation in temperature that occurs from the highs of the day to the cool of nights is called diurnal temperature variation. Temperature ranges can also be based on periods of a month or a year. The size of ground-level atmospheric temperature ranges depends on several factors, such as: Average air temperature; Average humidity
Thermal cross section with stronger lift (rising air) in darker shades of green, while red is sink (descending air). A thermal column (or thermal) is a rising mass of buoyant air, a convective current in the atmosphere, that transfers heat energy vertically. [1]
