Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1]
Heat haze, also called heat shimmer, refers to the inferior mirage observed when viewing objects through a mass of heated air. Common instances when heat haze occurs include images of objects viewed across asphalt concrete (also known as tarmac ), roads and over masonry rooftops on hot days, above and behind fire (as in burning candles , patio ...
Hot Stove is an offseason baseball talk show that airs on MLB Network and is simulcast on MLB Network Radio. The show offers the coverage of offseason activities including trades, free agent signings, and rumors. It is taped live in "Studio K" of the MLB Network studios in Secaucus, New Jersey.
Heat lightning (not to be confused with dry thunderstorms, which are also often called dry lightning) is a misnomer [1] used for the faint flashes of lightning on the horizon or other clouds from distant thunderstorms that do not appear to have accompanying sounds of thunder.

A stove fan is a fan which is placed on top of a heating stove to circulate air and improve efficiency. They are typically powered by the heat of the stove itself, mostly using a thermoelectric generator [1] but sometimes a Stirling engine.
Hot air ovens are electrical devices which use dry heat to sterilize. They were originally developed by Louis Pasteur , [ 1 ] and are essentially the same as fan ovens used for cooking food. Generally, they use a thermostat to control the temperature.
The heat generated from the welding tool was hot enough to cause the plastic lighter to melt and release its fuel, which ignited, causing a small explosion. A lighter can explode when put in a laundry dryer. Busted : A lighter was left in a running laundry dryer but suffered no significant damage and therefore did not explode.
In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect or Kelvin–Joule effect) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is expanding; typically caused by the pressure loss from flow through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment.
