The Use and Misuse of the LUWS of Thermodynamics
... then heat will flow spontaneously from the part with the higher T to the part with the lower T. If two parts of a hody separated by a movable wall or piston have different pressures (Fig. l b ) then work will flow spontaneously from the part with the higher P to the part with the lower P. If two par ...

First law of thermodynamics
... thermodynamic system is constant, it does zero work on the surroundings. Then W = 0, and For closed syst. in equilib., P-V work only w is zero In an isochoric process, all the energy added as heat remains in the system as an increase in internal energy. Heating a gas in a closed constant-volume cont ...

The Zeroth Law of Thermodynamics
... The Ideal Gas Temperature Scale is established using a single fixed point, the Triple Point of Water set at 273.16 Kelvin, and a constant volume gas thermometer. The degree on this scale is named after William Thomson, otherwise known as Lord Kelvin. (Think about how we get away with using a single ...
