state the low of the thermdynamics
Answers
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 any isolated system always increases.
The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Answer:
The laws of thermodynamics define physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems at thermodynamic equilibrium. The laws describe the relationships between these quantities, and form a basis of precluding the possibility of certain phenomena, such as perpetual motion. In addition to their use in thermodynamics, they are important fundamental laws of physics in general, and are applicable in other natural sciences.
Thermodynamics has traditionally recognized three fundamental laws, simply named by an ordinal identification, the first law, the second law, and the third law. In addition, after the first three laws were established, it was recognized that another law, more fundamental to all three, could be stated, which was named the zeroth law.
The zeroth law of thermodynamics defines thermal equilibrium and forms a basis for the definition of temperature: If two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other.
The first law of thermodynamics: When energy passes, as work, as heat, or with matter, into or out of 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.
The 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.
The third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches absolute zero.With the exception of non-crystalline solids (glasses) the entropy of a system at absolute zero is typically close to zero.
