Answer 1

hlo frd here is your ans we all know ' ?therm' mean heat dynamic mean motion it mean study of heat in motion .or transfer of heat from one form to another form of energy .
thermodynamic are two type :
1) classical thermodynamic : it give macroscopic point of view towards matter
2) statical thermodynamic : it give microscopic point of view towards matter
++ Law of thermodynamic --------------------+
1) first law of thermodynamic : according to this law energy neither be created and Nor be destroyed it can be transfer from one. form to another
dQ = dU + dW
according to equations an amount of heat is given to the system then it is the sum of increase in internal energy of a system and work done by system
2) second law of thermodynamic : acc to this law it is impossible for a self acting machine , operating in q cycle to transfer heat from cooler body to hot body . we all know heat move itself from hot body to cold body this mean some work has been done to transfer the heat from cooler to hot body . eg refrigerator
3) third law of thermodynamic :
we all know with the transfer of heat to a system the increase in entropy and molecules disorder is also increase acc to third law of thermodynamic at absolute temp the entropy of a system tends to zero and the molecules vof given system are in perfect order



:( :( plz is time ans delete my kerna but hard work legta h itna likne me ye copy nhi kiya hua . all are not same Moderater ji :( :(

$<b > Nice Question!!♡♡$

Thermodynamics is defined as “the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.

The laws of thermodynamics are stated below》》••

“Zeroth law of thermodynamics: If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.

First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.

Second Law of Thermodynamics: The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.

Third law of thermodynamics: As temperature approaches absolute zero, the entropy of a system approaches a constant minimum.
