A process for which this condition holds at all times is termed a quasistatic process.
A process for which this condition holds at all times is termed a quasistatic process. In thermodynamics, state functions are only defined in systems with this property. Under the IAU definition, if a body is subjected to gravitational and pressure gradient forces, then it must attain the hydrostatic type of this condition to be a planet. The (*) ​thermal type of this condition holds transitively, according to the zeroth law of thermodynamics. This condition arises at an extremum of potential energy, with maxima and minima corresponding to its stable and unstable types, respectively. For 10 points, name this motionless condition in which all the forces on an object sum to zero.
A process for which this condition holds at all times is termed a quasistatic process.
