First law of thermodynamics
... 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 container is an example of an isochoric process. (Note that there are types of work that do not involve a volume change. For example, we ...

... Deriving the ideal gas equation from kinetic theory Consider a cuboid, dimensions x,y,z, containing a single gas molecule of mass m travelling at speed v along the X direction. The molecule collides elastically with wall YZ and then travels in the opposite direction towards the other YZ wall. Q1. S ...

Efficiency and Open Circuit Voltage (OCV)
... Unfortunately, S and V are not easily measurable in most experiments (there is no such thing as an “entropy meter.”). Therefore, a new thermodynamic potential is needed equivalent to U but depending on quantities that are more readily measured than S and V. Temperature T and pressure P fall into thi ...
