Question

 In an open system, for maximum work, the process must be entirely

(a)irreversible

(b)reversible

(c)adiabatic

(d)none​

Answer 1

Answer:

c Adiabatic is the correct answer.........

Answer 2

"(b)reversible"

Explanation:

Reversible cycles produce the most extreme measure of work.

This is on the grounds that less hotness is lost to the environmental factors. So a reversible interaction (endlessly sluggish) accomplishes the most extreme work. There is one illustration of this that is straightforward: the work done by a gas extending inside a cylinder.

 

Envision that the forward response happens scarcely quicker than the converse response thus, all things considered, the response is at harmony. You can make the response invert by adding a minuscule measure of item or by eliminating a little measure of reactant. In this manner, a response at harmony is reversible! Then again, a response that isn't at harmony is irreversible. All genuine cycles are irreversible.

Assuming an interaction takes care of business on the environmental elements, you get more work out of the cycle on the off chance that it is done gradually. This is on the grounds that less hotness is lost to the environmental factors. So a reversible interaction (boundlessly sluggish) accomplishes the most extreme work. There is one illustration of this that is straightforward: the work done by a gas growing inside a cylinder. We will see that the greatest measure of work is acquired when the gas is permitted to grow gradually (reversibly).
