Question

(Q) q= -w is not true for :-
(1) Isothermal process
(2) Adiabatic process
(3) Cyclic process
(4) 1 and 3 both​

Answer 1

In the given question we have to find in which process the sum of total heat and total work done is equals to 0

therefore the answer is option 2.

this is because in adiabatic process there is no transfer of the heat energy .

ie

q=0

In an adiabatic process, energy is transferred to the surroundings only as work.
