System and surroundings — heat, work and the first law (3D)
About this app
A gas in a cylinder sits as the system in a water bath. Switch the type of system (open, closed, isolated) and the wall (diathermic, adiabatic); heat q and work w cross the boundary as visible energy packets. A ledger books q, w and ΔU with the Atkins sign convention; four examples from vacuum flask to car engine cylinder.
