Definiciones

Termal expansion: increased length, volume or other dimension metric suffers physical body due to temperature increase is caused in it by any means.

Thermal equilibrium: Two physical systems are in thermal equilibrium if no heat flows between them when they are connected by a path permeable to heat. Thermal equilibrium obeys the Zeroth Law of Thermodynamics. A system is said to be in thermal equilibrium with itself if the temperature within the system is spatially and temporally uniform.

Stage change: thermal phenomenon that a substance undergoes by altering their physical condition. Phases are states of matter which might require balance and thermal contact simultaneously.

boiling point is that temperature at which the vapor pressure of the liquid equals the vapor pressure of the medium in which it is located.

Fusión: is the temperature at which the balance is solid-liquid phases, namely solid matter passes to a liquid state, melts.

The latent heat is the energy required for a quantity of substance to change phase from solid to liquid (heat of fusion) or from liquid to gas (heat of vaporization). It should be noted that this energy as heat is reversed to the phase change and not to an increase in temperature.

three different mechanisms:

Driving: is the way to transfer heat from a body of higher temperature to one of lower temperature by direct contact.

Convection is a heat exchange between the air and a mass material which are at different temperatures.

Radiation: A mechanism of heat transfer in which the exchange occurs through the absorption and emission of energy by electromagnetic waves, so there is no need for a material means for transporting energy.
