The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of an isolated system always increases. The third law of thermodynamics states that the entropy of a system approaches...

There is basically four law of Thermodynamics. 1.Zeroth law of thermodynamics: If two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This law helps define the concept of temperature. 2.First law of thermodynamics: When energy passes, as work,...

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, and is equal to the natural logarithm of the product of the quantum ground states. read less

Four laws are there: 1. Zeroth law: If A and B are in thermal equilibrium and B and C are in thermal equilibrium, then A and C will also be in thermal equilibrium. 2. 1st Law: Energy can never be created nor be destroyed. It can only be transformed from one form to another form. The total energy in the...

It can only be transformed from one form to another form. The total energy in the Universe is constant. 3. 2nd Law: The entropy (randomness of a particle) of an isolated system, which is not in equilibrium, will increase and it will be maximum at equilibrium state. 4. 3rd Law: The entropy of a system is minimum and constant at an absolute zero temperature. read less

Zeroth law :- If two systems are both in thermal equilibrium with a third system then they are in thermal equilibrium with each other 1st law:- This states that energy can be neither created nor destroyed. However, energy can change forms, and energy can flow from one place to another. A particular...
read more Zeroth law :- If two systems are both in thermal equilibrium with a third system then they are in thermal equilibrium with each other 1st law:- This states that energy can be neither created nor destroyed. However, energy can change forms, and energy can flow from one place to another. A particular consequence of the law of conservation of energy is that the total energy of an isolated system does not change. Second law:- indicates the irreversibility of natural processes, and, in many cases, the tendency of natural processes to lead towards spatial homogeneity of matter and energy, and especially of temperature. It can be formulated in a variety of interesting and important ways. It implies the existence of a quantity called the entropy of a thermodynamic system. In terms of this quantity it implies that When two initially isolated systems in separate but nearby regions of space, each in thermodynamic equilibrium with itself but not necessarily with each other, are then allowed to interact, they will eventually reach a mutual thermodynamic equilibrium. The sum of the entropies of the initially isolated systems is less than or equal to the total entropy of the final combination. Equality occurs just when the two original systems have all their respective intensive variables (temperature, pressure) equal; then the final system also has the same values. third law:- The entropy of a perfect crystal of any pure substance approaches zero as the temperature approaches absolute zero. read less

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. 3. 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. 4. 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, and is equal to the natural logarithm of the product of the quantum ground states. read less
