In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasma and, to some extent, plastic solids. Although the term “fluid” includes both the liquid and gas stages, in common usage, “fluid” is often used as … Read more

The first law of thermodynamics is a version of the law of conservation of energy, specialized for thermodynamical systems. It is usually formulated by stating that the change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the … Read more

Last Updated: March 19, 2026 at 8:55 pmThermal radiation is electromagnetic radiation produced by the thermal motion of charged particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. The mechanism is that bodies with a temperature above absolute zero have atoms or molecules with kinetic energies which are changing, and these changes result in charge-acceleration and/or … Read more
