Consider a container with a frictionless piston that contains a given amount of CO₂ Assume that the behavior of this gas can be described by the van der Waals equation of state For carbon dioxide gas (CO₂), the constants in the van der Waals equation are a=0.364 J-m³/mol and b 4.27 x 10 m³/mol. Let's assume that initially the external pressure is 22.0 bar, which is the sum of a 1 bar atmospheric pressure and the pressure created by a very large number of very small pebbles that rest on top of the piston. The initial volume of gas is 0.5 L and the initial temperature is 25°C. Now, you will increase the volume of the gas by changing the external pressure slowly in a way that guarantees that the temperature of the system remains constant throughout the process. To do this, imagine you remove the pebbles one by one slowly to increase the volume by an infinitesimal amount. Every time you remove a weight you allow the system to equilibrate. Your cylinder is immersed in a water bath at 25°C, which keeps your gas at the same temperature throughout the whole process. Remember to use three significant figures for all numerical answers. The margin of error foreach (non-trivial) numerical answer is 1%. To avoid rounding errors use the unrounded intermediate values in your final calculations.
