What do you know about the laws of thermodynamics?



Basically there are three laws of thermodynamics which are called as first, second, and third law 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:

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

Second law of thermodynamics state that energy of natural system always remains on increasing level. This law is about the term entropy. Second law of thermodynamics is associated with the term irreversible reactions.

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 have 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.

First law of thermodynamics:



First law of thermodynamics is also called as law of conservation of energy which state that energy can never be destroyed but it can also be changed from one form to another form.

Applimentation of first law of thermodynamics:

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

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 than work done will always be positive. The amount of internal energy also increases. If energy is transferred from the system into the surroundings than work had done will always be negative. The amount of internal energy also decreases.

Second law of thermodynamics:



Second law of thermodynamics state that Entropy of a system always goes on increasing level. This law can be best explained in terms of measurement or degree of disorderness of a system.

Third law of thermodynamics:



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