EQUILIBRIUM
The condition of system in which all competing system are in balance.
LIST OF TYPES OF EQUILIBRIUM
1. MECHANICAL EQUILIBRIUM
A mechanical equilibrium is a state in which momentum of a particle , rigid body , system are conserved and net force zero .
F = 0
In the specific case linear momentum is zero and conserved is said to be static equilibrium .
EXAMPLE when a person press a spring,
2. CHEMICAL EQUILIBRIUM
The state in which the concentration of the reactants and products have stopped in time . This states results when the forward reaction proceeds at the same rate as the reverse reaction.
3. THERMAL EQUILIBRIUM
A state where an object and its surrounding cease to exchange energy in the form of heat it means they are in same temperature. Thermal are obeys zeroth law of thermodynamics . System in thermodynamic equilibrium always in thermal equilibrium.
4. THERMODYNAMIC EQUILIBRIUM
The state of thermodynamic system which is in thermal , mechanical and chemical equilibrium . when it is said that a system is simple in equilibrium .
