Laws of thermodynamics


Basically, there are three laws of thermodynamics which are called the first, second, and third laws of thermodynamics. All of these laws are widely applicable in our study but on the other hand other is another law which is called as zero law of thermodynamics.

Laws of thermodynamics:

The first law of thermodynamics state that Energy can neither be created nor destroyed but can also is converted from one form to another form. This law is also called the law of conservation of energy.

The second law of thermodynamics state that the energy of a natural system always remains at an increasing level. This law is about the term entropy. The second law of thermodynamics is associated with the term irreversible reactions.

The third law of thermodynamics states that While the entropy of each and each element (in their perfectly crystalline states) is taken as 0 at absolute 0 temperature, the entropy of each substance has to have a tremendous, finite price. But, the entropy at absolute 0 can be identical to 0, as is the case when an ideal crystal is taken into consideration.

The first law of thermodynamics:

The first law of thermodynamics is also called as law of conservation of energy which states that energy can never be destroyed but can also be changed from one form to another form.

Implementation of the first law of thermodynamics:

The first law of thermodynamics can also be well applied in our common use. For example, we use a lamp for light by mechanical energy it converts it into electrical energy.

The first law of thermodynamics also tells us about the nature of work

We relate this term with the transfer of energy if energy is transferred from the surroundings into the system then work done will always be positive. The amount of internal energy also increases. If energy is transferred from the system into the surroundings then work had done will always be negative. The amount of internal energy also decreases.

The second law of thermodynamics:

The second law of thermodynamics state that the Entropy of a system always goes on an increasing level. This law can be best explained in terms of measurement or degree of disorderliness of a system.

Third law of thermodynamics:

Third law of thermodynamics state that the Entropy of any system reaches a constant value at absolute temperature. The entropy of a system always remains zero at absolute temperature.
