You're videos are so cool omg! I've recently studied Thermodynamics and States of matter in school and I wasn't really a big fan of Thermodynamics, I was the person who'd fear chemistry, but seeing your videos being recommended to me by youtube, I feel incredibly curious and excited to study chemistry! Thanks a lot! Your channel is seriously too underrated no kidding. I really hope you continue making these kinds of videos though, people are definitely going to notice your channel! It seriously feels impossible to stop after you get so hooked onto watching your videos!
A quick analogy can be used here with Physics and Chemistry concepts. Work as defined in Physics is: Work = F x d. An external force must act on an object (the system) and that force must move that object (system) over a distance. So in the very least, there must be an interaction of the system (inside of the system) and an external force (outside) over a distance so that there would be work. For the case of work calculations in thermodynamics, gases are the common systems. With our original analogy, the pressure of the gas (internal pressure) must be acted/counteracted on by a force from the outside and move the piston/container boundary to produce work. A pressure applied on the defined area of the gas piston is dimensionally equivalent to an applied force because Pressure = Force/Area which rearranges to Force = Pressure x Area. Hope this explanation helps you out.

man your videos are so so goof
good* please keep making them
Why is external pressure used in calculating work
