Question

Its urgent

Please explain me the laws of thermodynamics ??​​

Answer 1

Answer :----

#The Laws of Thermodynamics :——

✨0 law of thermodynamics : – If two thermodynamic systems are each in thermal equilibrium with a third then they are in thermal equilibrium with each other.

⭐The first law is also known as Law of Conservation of Energy.

➡That states that the energy cannot be created or destroyed in an isolated system.

⭐2nd law of thermodynamics states that when energy changes from one form to another form

✨➡ or matter moves freely, entropy in a closed system increases.

✨ Differences in ⤵⤵

➡ temperature,

➡pressure,

➡density tend to even out horizontally after a while.

⭐3rd law of thermodynamics states that the entropy of a system at absolute zero is a well-defined constant.

✨This is because a system at zero temperature exists in its ground state.

⭐Or in very short As temperature approaches absolute zero, then the entropy of a system approaches a constant minimum.

➡The three laws of thermodynamics define physical quantities (temperature, energy, and entropy) that characterize thermodynamic systems at thermal equilibrium. The laws describe how these quantities behave under various circumstances, and preclude the possibility of certain phenomena (such as perpetual motion)

The three laws of thermodynamics are :-

# First law of thermodynamics :- When energy passes, as work, as heat, or with matter, into or out from a system, the system's internal energy changes in accord with the law of conservation of energy. Equivalently, perpetual motion machines of the first kind (machines that produce work with no energy input) are impossible

# Second law of thermodynamics :- In a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems increases. Equivalently, perpetual motion machines of the second kind (machines that spontaneously convert thermal energy into mechanical work) are impossible

# Third law of thermodynamics :- The entropy of a system approaches a constant value as the temperature approaches absolute zero.[2] With the exception of non-crystalline solids (glasses) the entropy of a system at absolute zero is typically close to zero
