Linked Question 1

The pair of isochoric processes among the transformation of states is :

L to M and N to K

L to M and M to N

M to N and N to K

K to L and L to M

Volume constant in N to K and L to M

Linked Question 2

The succeeding operations that enable this transformation of states are :

Cooling, heating, cooling, heating

Cooling, heating, heating, cooling

Heating, cooling, heating, cooling

Heating, cooling, cooling, heating

K → L : ideal gas

P constant, n constant

V increases, temperature also increase

$∴$ Heating Rejecting (B) and (D)

Checking M to N, P constant V decreases, n constant

Temperature decreases $∴$ cooling
