Quasi-static process

Such a process occurs when the system proceeds in such a way that it remains infinitesimally close to an equilibrium state throughout the process.

Instructions:
Assuming the points I and F, the initial and final states of a process respectively.

• User has to click and drag the mouse cursor from point I to F without a break.
• The drag speed must be appropriate for equilibrium which will give a series of black dots every second.
• If one moves too fast, dot the will turn in to blue filled circles.
