Thermodynamics is the science that studies the work and heat exchange between a system and its environment.

First Law: This law states that the amount of energy does not change in any system remains constant from that can only be transformed.

System: is an amount of material chosen for the study

Closed system: when there is no exchange of mass, only energy exchange.

Isolated system: when there is no exchange of energy or mass.

Open system: when there are energy and mass exchange between the environment and the system.

Surroundings: region outside the system.

border: surface separating the system from its surroundings:

Process: is any change that you experience a system from one equilibrium state to another:

Background: A series of state at which the system during a process step.

Properties: they are variables that is used to describe the state of any system.

Intensive variables: do not depend on the size of a system such as temperature, pressure, density

Extensive variables are those which depend on the size of the system.

Types of processes

Or thermal processes is: the temperature of the system remains constant:

Isoborico process: the system pressure is constant

Isometric process, the volume remains constant.

Adiabotico process: a process where there is no heat transfer

Quasistatic process: process that allows an internal adjustment

State equilibrium is a state of balance

Thermal equilibrium: when the temperature is the same throughout the system

Mechanical equilibrium is said that is when there is no change with pressure at any point in the system

Phase equilibrium: when the mass of each phase reached an equilibrium level.

Chemical equilibrium: when its chemical composition does not change with time.

Energy: the capacity to do work (light, heat, electricity)

Pressure: force exerted by a fluid per unit area

Zeroth Law: This law is based on the temperature of bodies, that is, if the bodies with different temperatures are put into contact at certain points reach the same temperature.

Pure substance: substance that has a fixed chemical composition.

One or more pure blends can be provided that are homogeneous

Print saturation temperature of saturation:

Saturation temperature is the temperature at which a substance changes phase to a certain pressure

Saturation pressure: the pressure at which a substance changes phase. Temperature is right,
