Document Summary
: gas trapped in a piston is a closed system: types of systems- Isolated system-nothing can pass; can"t perform work a: closed system-some things can pass, energy can be transferred through work, there are any types of work. : expansion/compression of gases illustrate the properties of work: types of work, definition of work: the force * displacement. : moving a table-going against the force of gravity x amount displaced from original position to current positon. : if you push on a table, you"re performing work, so w = + Lecture 2: e in a system occurs via work and heat. If work is performed by the system, work is negative. In piston-constant pressure is applied to gas during combustion is pext (piston has no weight: blowing up a balloon-pext is atmospheric pressure and elasticity of the balloon, boling a liquid-pext is atmospheric pressure, example of pv work:
