An ideal gas undergoes a four step cycle as shown in the P – V diagram below. During this cycle, heat is absorbed by the gas in

a
steps 1 and 2
b
steps 1 and 3
c
steps 1 and 4
d
steps 2 and 4

detailed solution

Correct option is C

→ in the path (1) volume of an ideal gas is increasing at constant pressure.∵V∝T=dQ is +ve (absorbed)In the path (4) pressure of an ideal gas is increasing at constant volume ∵P∝T=dQ is +ve (absorbed)
