 # A Brief Overview of Thermodynamics

Thermodynamics: General Description Thermodynamics: General Definition Thermodynamics describes the study of how certain processes change their conditions by altering their underlying laws of thermal equilibrium. The term thermodynamics comes from a Greek term, thmosmos, which means heat and kinos which mean electricity. Rather than being classified under the natural chemistry family, thermochemistry is actually a branch of the physics department. In essence, thermochemistry is a science that studies the changes in heat, pressure, and temperature on the macroscopic level using a number of different scientific principles.

A fundamental principle of thermodynamics relates to the energy levels of various substances. These energy levels can be in one of three states, called the ‘equilibrium’, the ‘stasis’ or the ‘hyperbolic’ state.

There are two main ways that equilibrium states can change. They can either decrease or increase the level of energy, while other processes such as evaporation, melting, expansion, etc can alter the environment in which the process occurs.

A major reason why energy states change is because the laws of thermodynamics are able to determine the probability of these states occurring. The law of thermodynamic equilibrium tells us that the likelihood of any process occurring is dependent on its energy state and its temperature. Therefore, we can predict exactly how many times a particular process will occur and how much heat it will produce.

If we want to understand what causes an increase in the chances of thermodynamic equilibrium, we need to first understand the concept of conservation of energy. The laws of thermodynamics state that if the total amount of energy in a system is greater than the total amount of energy required to create it, then the process will stop, so long as the heat is not lost.

In thermodynamics, heat is said to be ‘added’lost’ from a system when it is converted into energy. This ‘conversion’ occurs in a process known as ‘chemical reaction’. The molecules in a substance react together and produce energy when they combine.

When this happens, some of the substance’s molecules (reactions) become free of energy whilst others become free of energy, causing the substance to change into a different state of being. These new, energy-free molecules (called carriers of heat) are known as ‘virtual carriers’ of heat. If there are more virtual carriers of heat than real carriers of heat, then the process will be ‘continued’ and the system will reach equilibrium.

We know that there are four types of energy in a substance. Two types of energy are ‘internal’ and one type is ‘external’. Internal energy is known as internal and external energy is known as external. The type of energy that we are familiar with comes from heat radiation from the sun, the universe, space, and from atomic reactions.

There are four different types of energy, which are known as thermal energy, potential energy, kinetic energy, and potential power. Thermal energy is the amount of energy which can be produced in the process of heating up a substance. Potential energy is the amount of energy which is lost during the process of cooling. Kinetic energy is the energy that can be produced in a substance, whether or not it is heated or cooled.

Kinetic energy is also known as energy, which is used to propel the object that is being moved. It can be used to transfer force from one body to another. This is commonly used in motion.

Thermodynamics involves finding the relationships between the different forms of energy in a substance. This means that in order to have an understanding of thermodynamics, we have to understand what each form is and how it changes through time. These relationships can be used to determine the probability of a process occurring. We can then use these probabilities to predict the behavior of the system.

The concept of thermodynamics is also used to make predictions regarding a substance’s temperature. By using equations in thermodynamics, scientists can determine what temperatures a substance can maintain without losing any of its internal energy. The temperature limit is known as the thermodynamic limit.
