Best ResponseYou've already chosen the best response.0In an isolated system, dQ and dW are zero because there is no change in heat or work.

Best ResponseYou've already chosen the best response.0how no change in work...i can understand that dq is 0..but please explain that hoe dw is 0

Best ResponseYou've already chosen the best response.0given\[W=\delta E_k=1/2*m*(v_2^2v_1^2)\]as there is no external force (heat, pressure, etc.) the average velocity of the atoms will not change (some might speed up or slow down as they hit each other, but the average stays the same).

Best ResponseYou've already chosen the best response.0What you mean it say is the the change in energy is zero for an isolated system, and that heat and work must both appear at the boundary of a system, because by definition they measure flows of energy across the boundary.
