Del, or nabla, is an operator used in mathematics, in particular in vector calculus, as a vector differential operator, usually represented by the nabla symbol ∇.
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
In mathematics, physics, and engineering, a Euclidean vector (sometimes called a geometric or spatial vector, or—as here—simply a vector) is a geometric object that has magnitude (or length) and direction.
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems.
Flux describes the quantity which passes through a surface or substance.
A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor.
The International System of Units (SI, abbreviated from the French Système international (d'unités)) is the modern form of the metric system, and is the most widely used system of measurement.
Latent heat is thermal energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.
In mathematics, Monte Carlo integration is a technique for numerical integration using random numbers.
In radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted or received, per unit time, and spectral flux or spectral power is the radiant flux per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
The rate of heat flow between two systems is measured in watts (joules per second).
Relativistic heat conduction refers to the modelling of heat conduction (and similar diffusion processes) in a way not compatible with special relativity.
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
Solar irradiance is the power per unit area received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument.
Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma).
The square metre (International spelling as used by the International Bureau of Weights and Measures) or square meter (American spelling) is the SI derived unit of area, with symbol m2 (Unicode character). It is the area of a square whose sides measure exactly one metre.
Thermal conduction is the transfer of heat (internal energy) by microscopic collisions of particles and movement of electrons within a body.
Thermal conductivity (often denoted k, λ, or κ) is the property of a material to conduct heat.
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple.
A thermopile is an electronic device that converts thermal energy into electrical energy.
Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.
The watt (symbol: W) is a unit of power.
