The universe is made of energy and matter (which itself is a condensed form of energy). Energy alfa tech india can not be created or destroyed but can take many forms and change from one form to another type.
Matter itself has internal energy and particles are in constant motion. An isolated body retains its internal energy. Anywhere in the universe where matter exists, there will be a measurable amount of heat energy.
When a particle "energized" contact less energized particle will happen a 'thermal transfer alfa tech india "particle energy" hot "to" cold "particle until both particles reach an average level of energy called" thermal equilibrium ".
The particle "energized" apply a force to the "less energized" by increasing its rate of vibration, so that the particle will require more space, and leave the balance in which it was before being energized.
At the same time, will occur a "waste heat" to come off in different "bosons" of energy alfa tech india called "phonon" alfa tech india .The process of energy transfer is accomplished in two basic ways: by "driving" alfa tech india (enthalpy) in which includes "convection" or "radiation" (entropy).
In fluids (liquids alfa tech india or gases) classical physics calls this phenomenon "convection". As molecular alfa tech india fluid forces are weaker, the excitation of the particles increases the pressure on the walls of its container, generating kinetic alfa tech india energy in the particles with mass interacts with other forces causing the movement of atoms and molecules a cold to a point hottest point.
Radiation heat transfer alfa tech india is via electromagnetic waves where the phonon needs no medium for transferring energy from the emitter to the absorbent. One example is the energy from the Sun to the Earth heat.
The "specific heat" of a material is the ability of a unit mass of the material for energy or heat to raise its temperature 1. This varies according to the density of matter.
These turning points are: melting alfa tech india (solid -> liquid), freezing (liquid -> solid), evaporation (liquid -> gas), condensation (gas-> liquid), sublimation (solid <-> gas) or ionization ( gas-> plasma) alfa tech india according to the change.
The unit of measure of the "warmth" is the same as that of "energy" and "work": alfa tech india the joule, but also commonly use the "calorie". As the value of such a small Coloria normally use the nutrition value of kilocalorie (1,000 calories).
