Question

3.
The incorrect statement is
adiabatic
(1) Wrev> Wir in isothermal process
(2) AU = w
(3) q = 0 for cyclic process
(4) Work and heat appear only at the boundary of
the system​

Answer 1

Answer:

In the give question we have to find in which process the sum of total heat and total work done is equal to O

therefore the answer is option 2.

this is because in adiabatic process there

is no transfer of the heat energy

i.e.

q=O

In an adiabatic process, energy is

transferred to the surroundings only as

work
