Question

What is thermodynamics? What are the two laws of thermodynamics?​

Answer 1

Answer:

The laws of thermodynamics define fundamental physical quantities (temperature, energy, and entropy) that characterize thermodynamic systems.

Explanation:

• 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 2

What is thermodynamics ?

• Thermodynamics, science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another.

• Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy. In particular, it describes how thermal energy is converted to and from other forms of energy and how it affects matter.

Two laws of thermodynamics :-

• The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes, distinguishing two kinds of transfer of energy, as heat and as thermodynamic work, and relating them to a function of a body's state, called Internal energy.

• The second law states that if the physical process is irreversible, the combined entropy of the system and the environment must increase. The final entropy must be greater than the initial entropy for an irreversible process: Sf > Si (irreversible process)
