Question

I am new and nobody answerung me

Please explain me the laws of thermodynamics ??

Answer 1

#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.

____________________________________

$\bf \large Thermodynamics$

The Branch of Physics that deals with heat and temperature, and their relation to Radiation, Work, Energy and Properties of bodies of matter is called Thermodynamics.

____________________________________

$\bf \large Thermal \: Energy$

Thermal Energy is the Energy a Substances or System has due to its Temperature, that is, the Energy of Moving or Vibrating Molecules, according to the Energy Education Website of the Texas Education Agency.

$\huge \boxed{\rm The \: Three \: Law \: of \: Thermodynamics}$



$\textsf{The fundamental principles of thermodynamics were} \\ \textsf{originally expressed in three laws.}$


$\bullet \: \textbf{The Zeroth Law of Thermodynamics}$

The Zeroth Law states that if two bodies are in thermal equilibrium with some third body, then they are also in equilibrium with each other.


$\bullet \: \textbf{The First Law of Thermodynamics}$

The First Law states that the total increase in the energy of a system is equal to the increase in thermal energy plus the work done on the system.


$\bullet \: \textbf{The Second Law of Thermodynamics}$

The Second Law states that heat energy cannot be transferred from a body at a lower temperature to a body at a higher temperature without the addition of energy.


$\bullet \: \textbf{The Third Law of Thermodynamics}$

The Third Law states that the entropy of a pure crystal at absolute zero is zero. is also a measure of the disorder in a system, and while a perfect crystal is by definition perfectly ordered, any positive value of temperature means there is motion within the crystal, which causes disorder.
