Piston Diagram

Postby Jasmine Cha 1A » Fri Jan 20, 2017 10:55 pm

Hi, for the visual diagram provided on p.9 of the course reader, could someone explain what the surface area is referring to, and how that relates to a volume change? Thanks!

For that diagram, A refers to the area of the top of the cylinder (the circular part).
If you multiply that area by the distance the piston moves due to external pressure, you'd get the change in volume.
