Question

Match the following lists:

List - I		List - II
(A)	Zeroth law of Thermodynamics	(I)	Direction of flow of heat
(B)	First law of thermodynamics	(II)	Work done is zero
(C)	Free expansion of a ga s	(III)	Thermal equilibrium
(D)	Second law of Thermodynamics	(IV)	Law of conservation of energy

The correct answer is

• A. (A)- (II) , (B)-(IV) , (C)-(III) , (D)-(I)
• B. (A)-(III) , (B)-(IV) ,(C)-(II) , (D)-(I)
• C. (A)-(III) , (B)-(I) , (C)-(II) , (D)-(IV)
• D. (A)-(I) , (B)-(III) , (C)-(IV) , (D)-(II)

Answer 1

Answer: (B)

(i) Zeroth law of thermodynamics states about thermal equilibrium of different states in contact.
(ii) First law is energy conservation law.
(iii) In free expansion of gases, work done is always zero.
(iv) Second law of thermodynamics discusses about flow of heat in thermal bodies.
