v. t. e. The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [ 1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a ...
Cute aggression, or playful aggression, is the urge to squeeze or bite things perceived as being cute without the desire to cause any harm. It is a common type of dimorphous display, where a person experiences positive and negative expressions simultaneously in a disorganised manner. [1]
Thermocouple. A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature.
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics, which convey a quantitative description using measurable macroscopic physical quantities ...
Thermosetting polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer ( resin ). [ 1] Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst.
Thermoelectric cooling. Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending ...
Thermally modified wood. Beechwood processed at different temperatures. From left to right: 200 °C, 190 °C, untreated. Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere.
Thermosiphon. Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces ...
