(a) Explanation The P V diagram for the work done is between points A to point C is shown in the figure below. Figure (1) The area under the P V diagram shows the work done on expanding the gas. The formula to calculate the work done is, W = ( P Δ V ) rect ( AK6EA ) + ( P Δ V ) tri ( MBK ) (1) The formula to calculate the work done is, W = ( P Δ V ) rect ( AK6EA ) = P ( V f − V i ) Here, P is the pressure. V f is the final volume. V i is the initial volume. Substitute 200 kPa for P , 6 m 3 for V f and 2 m 3 for V i in above equation to find ( P Δ V ) rect ( AK6EA ) . W = ( 200 kPa × 10 3 Pa 1 kPa ) ( 6 m 3 − 2 m 3 ) = 0.8 × 10 6 J (2) The formula to calculate the work done is, W = ( P Δ V ) tri ( MBK ) = 1 2 ( P f − P i ) ( V f − V i ) Here, P f is the final pressure (b) To determine Whether the work done depends on the fluid being an ideal gas or not

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…
