Question
In the example shown in the figure, (Figure 1) the "container" is a cylinder whose volume changes as the piston slides in or out. Suppose a gas is confined within the cylinder. The pressure of the gas is , and the area of the cylinder is . Consider the work done as the gas expands, pushing the piston to the right. Call the small distance that the piston moves . What force does the gas exert on the piston? (Note that the positive x axis is to the right in the figure.) express units in terms of p, A and any contants.Explanation / Answer
force exerted by gas = pressure*area. no constant involved here.
