Math Solution of Fluid

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…

Heat and gas

Generally, when substances are heated, their particles begin to move faster. In solids, molecules vibrate together; heat makes them vibrate harder Heat and gas Heat and gas Heat and gas Heat and gas Heat and gas To Download Heat and Gas Click Here Generally, when substances are heated, their particles begin to move faster.

Temperature

Temperature is a physical quantity that is a measure of hotness and coldness on a numerical scale. It is a measure of the local thermal energy of matter or radiation; it is measured by a thermometer, which may be calibrated in any of various temperature scales, Celsius, Fahrenheit, Kelvin, etc., etc. Empirically it is found…

Heat Radiation

Thermal 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…

Math Solution of Heat Radiation

Radiation heat transfer is concerned with the exchange of thermal radiation energy between two or more bodies. Thermal radiation is defined as electromagnetic radiation in the wavelength range of to 100 microns (which encompasses the visible light regime), and arises as a result of a temperature difference between 2 bodies. No medium need exist between the two…

Change of State

A snowman, glass of water and steam might look very different but they are made of the same stuff! Just like any substance, water can exist in three different forms, called states: solid, liquid and gas. The state will change when the substance is heated. Change of State As a solid, a substance has a…
