Question

✌✌ga guys...
↪️An ideal gas undergoes four different processes from the same initial state (Fig. 12.1). Four processes are adiabatic, isothermal, isobaric and isochoric. Out of 1, 2, 3 and 4 which one is adiabatic.


(a) 4

(b) 3

(c) 2

(d) 1

​

Answer 1

During an adiabatic process, no heat is transferred to the gas, but the temperature, pressure and volume of the gas changes.

The curve on a p-v diagram is equal to the work performed by a gas during the process.

∴ curve 2 shows the adiabatic process.

Hence option is correct.
