Types of Equilibrium. Macroscopic Properties such as Temperature Pressure or Density Should Not Change With Time. A system should be at rest in the absence of any external force. Consider a Tank of water from which water. is flowing out of a pipe at Steady state, The water level is maintained by another pipe adding water to the Tank. Although The amount of water remains constant, this is Not a State of equilibrium, Such a system is Said to be in a Steady state. A True State of equilibrium in Thermodynamics is Characlarized by Mechanical, thermal as well as Chemical equilibrium. Mechanical Eequilibrium means that there wre No Unbalanced forces inside the system and Nove Between the System and sulloundings. Thermal equilibrius requires that all ports of the system are at the same Temperature. Chemical equilibrium means that there ve No sponteneous Changes System and Identical Chemical IM the These are three possible ways ball can rest and More d a Steed on a Concave, Conver less level Surface. al is an example of Stable equilibriun as the gravity ensures that the ball Stays at the bottom. b) shows the steel ball at the top of a curved Surface, The ball will fall either way at the slighast application of force → unstable equilivslinn. C) Thee ball appears to be stable but can easily be made to fall o88, This is an example of Metastable equilibriom
