The video tutorial by Kevin Tolkoff introduces the concept of work in thermodynamics, contrasting it with classical physics. It explains how work is calculated using force and distance in classical physics and how this differs in thermodynamics, especially when dealing with gases. The tutorial uses a cylinder and piston example to illustrate changes in volume and pressure, leading to a mathematical derivation of work. It also covers the sign convention for work in chemistry and introduces the concept of isochoric processes, where volume remains constant, resulting in no work done.
