Question

One mole of a monatomic ideal gas undergoes the cyclic process J→ K→ L→ M→ J, as shown in the P-T diagram.Match the quantities mentioned in List-I with their values in List-II and choose the correct option.

Match the quantities mentioned in List-I with their values in List-II and choose the correct option. [ℛ is the gas constant.]

List-I	List-II
P	Work done in the complete cyclic process
Q	Change in the internal energy of the gas in the process JK
R	Heat given to the gas in the process KL
S	Change in the internal energy of the gas in the process MJ

• A. ) P → 1; Q → 3; R → 5; S → 4
• B. P → 4; Q → 3; R → 5; S → 2
• C. P → 4; Q → 1; R → 2; S → 2
• D. P → 2; Q → 5; R → 3; S → 4

Answer 1

Answer: (B)

P → 4; Q → 3; R → 5; S → 2

Answer 2

The correct option is (B):P → 4; Q → 3; R → 5; S → 2
