Apparent temperature was invented by Robert Steadman [3] who published a paper about it in 1984. [4] However, it also applies to indoor temperatures, especially saunas, and when houses and workplaces are not sufficiently heated or cooled. The heat index and humidex measure the effect of humidity on the perception of temperatures above +27 °C ...
Since water is much denser than air, much greater changes in ambient pressure can be experienced under water. Each 10 metres (33 ft) of depth adds another bar to the ambient pressure. Ambient-pressure diving is underwater diving exposed to the water pressure at depth, rather than in a pressure-excluding atmospheric diving suit or a submersible.
Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor.
T 0 = original temperature, T R = ambient temperature, t = time. In 1701, Isaac Newton anonymously published an article in Philosophical Transactions noting (in modern terms) that the rate of temperature change of a body is proportional to the difference in temperatures (graduum caloris, "degrees of heat") between the body and its surroundings ...
The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).

Over time, researchers have consistently encountered superconductivity at temperatures previously considered unexpected or impossible, challenging the notion that achieving superconductivity at room temperature was infeasible. [4] [5] The concept of "near-room temperature" transient effects has been a subject of discussion since the early 1950s.
NaK is 40–90% potassium and it is liquid at ambient temperature. It is an excellent thermal and electrical conductor. It is an excellent thermal and electrical conductor. Sodium-calcium alloys are by-products of the electrolytic production of sodium from a binary salt mixture of NaCl-CaCl 2 and ternary mixture NaCl-CaCl 2 -BaCl 2 .
However, chemical analysis of Martian meteorite samples suggests that the ambient near-surface temperature of Mars has most likely been below 0 °C (32 °F) for the last four billion years. [ 10 ] Some scientists maintain that the great mass of the Tharsis volcanoes has had a major influence on Mars' climate.
