Answer 2

Explanation:

First law of Thermodynamics -

Energy of universe is always conserved or total energy of an isolated system is always conserved

delta E = q + W

- wherein

delta E = Internal Energy

q = Heat

W= work

Adiabatic Process -

Heat exchange between system and surrounding is zero i.e.

q= 0

wherein,

delta E = q+ w

q=0

delta E = w

therefore, Correct option is ii) q=0

hope it helps u mate ☺
