Difference Between Adiabatic, Isothermal,

Thermodynamics is an important topic of physics. This helps explain different conditions and states of a matter while using heat. This heat can be used in various ways. The heat makes some differences in that matter or to be more precise to a system. These changes are for various processes involved in thermodynamics.

Some processes work on the temperature, some processes work on the pressure. So, different processes work in different characteristics of a system in thermodynamics. It is really important to know the differences between the different processes of thermodynamics.

Thermodynamics

Thermodynamics is that branch of physics, where the relationship between heat, temperature, work, and energy get studied. There are various processes involved in thermodynamics. Those processes have been differentiated based on their characteristics. Also, there are different laws of thermodynamics. 

The law of thermodynamics describes the internal energy of the system. If the energy of the system gets changed, is the system performing enough to justify the changes of energy that occurred due to external heat or energy applied. According to thermodynamics, the energy of any system can’t be created or destroyed, it can only be transferred from one form to another.

Different Processes of Thermodynamics and their Differences

As stated earlier, there are various processes involved in thermodynamics based on their characteristics, and obviously, there will be some differences between those. The processes are adiabatic, isothermal, isobaric, and isochoric. Based on their characteristics there are differences between these processes, it is also important to know a few details about these processes.

Adiabatic process

This process of thermodynamics is based on heat. In this process no matter how differently heated systems are kept together, there will be no heat exchange at all. In other words, in an adiabatic process, no heat transfer takes place for a particular system, if also they have been kept in direct contact. That means, no heat goes out from the system, or no heat comes inside the system. This process remains heat resistant completely. In this process, the system transfers the energy only in terms of performing work.

Isothermal Process

The word thermal denotes the temperature. This process is also related to the temperature of the system. Isothermal is completely the opposite of the adiabatic process. In this process, the temperature of a process always remains constant. This implies, there is a constant heat exchange that gets performed for that particular system. The system adopts the change of heat so slowly in the isothermal process, it helps the system to keep the temperature constant. Along with that, this heat exchange explains the change in internal energy for that particular system under the isothermal process.

Isobaric Process

Baric means pressure, and isobaric is that process in those various processes involved in thermodynamics, where the pressure of the system remains the same. Unlike the last two, this process is related to the pressure of the system. Though pressure remains constant for that particular system, there is an exchange of heat, which causes the work to be performed by the system. This heat exchange also helps in changing internal energy.

Isochoric Process

This process is completely different from the rest of those three processes. The isochoric process also can be called the isometric process. This is also one of the various processes involved in thermodynamics. In this process, neither the temperature nor the pressure remains constant, instead of these two the volume of the system remains constant. With the help of this process of thermodynamics, the system undergoes in such a way, where the volume of the system remains the same, but the changes in heat perform the work, and the changes in internal energy are completely measurable.

Difference Between Isothermal and Adiabatic Process

The basic difference between both the processes is the temperature. In the adiabatic process, the heat doesn’t get exchanged at all for the system. No matter what, you will not be able to experience a bit of change in heat in the system, it will be constant. It will only exchange the energy to perform the work. On the other hand, in the isothermal process, there will be an exchange of heat, but the temperature of the system will remain constant, with the help of slow adaptation of the temperature.

Differences Between Isochoric and Isobaric Process

In the Isobaric process, the pressure of the system will remain constant. There will be a change in temperature, volume, and internal energy, but the pressure will not be changed. But in the isochoric process, the volume of the system will remain constant. Heat can change the pressure, temperature, or internal energy, but in this process, the volume of the particular system will be the same. So, in a nutshell, the difference between various processes involved in thermodynamics is for Adiabatic, the heat doesn’t get exchanged, whereas for isothermal the heat gets exchanged, but the temperature remains constant. For isochoric the constant is the volume of the system, and for isobaric, the constant is the pressure.

Conclusion

Among various processes involved in thermodynamics, the common is the relationship between heat, temperature, work, and internal energy. The difference gets created when these factors affect the changes in the system. Based on the changes in the system and most importantly the constant of a system, creates the difference between those different thermodynamic processes.
