The terms sensible heat and latent heat refer to energy transferred between a body and its surroundings, defined by the occurrence or non-occurrence of temperature change; they depend on the properties of the body. Sensible heat is sensed or felt in a process as a change in the body's temperature.
The Bowen ratio is calculated by the equation: =, where is sensible heating and is latent heating. In this context, when the magnitude of is less than one, a greater proportion of the available energy at the surface is passed to the atmosphere as latent heat than as sensible heat, and the converse is true for values of greater than one.
The sensible heat of a thermodynamic process may be calculated as the product of the body's mass (m) with its specific heat capacity (c) and the change in temperature (): =. Joule described sensible heat as the energy measured by a thermometer. Sensible heat and latent heat are not special forms of energy. Rather, they describe exchanges of ...

The ice had thus absorbed 8 “degrees of heat”, which Black called sensible heat, manifest as temperature change, which could be felt and measured. In addition to that, 147 – 8 = 139 “degrees of heat” were absorbed as latent heat, manifest as phase change rather than as temperature change. [22] [26]
Here’s how extreme heat affects sleep — and how to ... temperatures have made people around the world sleep an estimated 44 hours less a year in the beginning of the 21st century. If ...
People are highly sensitive to even small differences in environmental temperature. At 24 °C, a difference of 0.38 °C can be detected between the temperature of two rooms. [4] The Predicted Mean Vote (PMV) model stands among the most recognized thermal comfort models.
In physiology, thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux.It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate defense response.
