Question

Give the statementss of Zeroth,First, second and third laws of thermodynamics and outline their significant

Answer 1

• 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.
• The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. The total amount of energy in an isolated system is conserved
• 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.  Simply: the entropy of an isolated system only increases and never decreases.
• The third law of thermodynamics states that the entropy of a system approaches a constant minimum as the temperature approaches absolute zero.
