The refractive index of water at room temperature (25°C) is a standard value of 1.333. This value indicates the ratio of the speed of light in a vacuum to its speed in water. It is a fundamental property used in optical experiments and calculations.
A thermodynamic system is taken through the cyclic process \(ABC\) as shown in the \(P\!-\!V\) diagram. The total work done by the system during the cycle \(ABC\) is _______ J. 
Given: The area enclosed by the cycle in the \(P\!-\!V\) diagram represents the work done.
