The equation for calculating the work performed when a piston in a cylinder expands against a constant pressure is w = −P ∙ΔV, where ΔV is the change in volume inside the cylinder. How much work is performed (in joules) when a piston pushes against a constant pressure of 1.21 atm, resulting in a volume change of 2.56 mL? (Hint: First determine the units that must be used for each term in the equation.)(101,325 Pa = 1 atm)
