Question

A fixed mass 'm' of a gas is subjected to transformation of states from K to L to M to N and back to K as shown in the figure.
The succeeding operations that enable this transformation of states are:

• A. heating, cooling, heating, cooling
• B. cooling, heating, cooling, heating
• C. heating, cooling, cooling, heating
• D. cooling, heating, heating, cooling

Answer 1

The correct option is C heating, cooling, cooling, heating


K→L⇒ Isobaric process, V is increasing with increase in temperature according to Charle's law ⇒Heating
L→M⇒ Isochoric process, P is decreasing with decreasing temperature according to Gay lussac's law ⇒Cooling
M→N⇒ Isobaric process, V is decreasing with decrease in temperature according to Charle's law ⇒Cooling
N→K⇒ Isochoric process, P is increasing with increasing temperature according to Gay lussac's law ⇒Heating
