- Published on 20 Aug 15

a. mechanical equilibrium
b. chemical equilibrium
c. thermal equilibrium
d. all of the above

ANSWER: all of the above
 
When a system does not have any unbalanced force within itself and also between the system and its surrounding then the system is in the mechanical equilibrium. When there is no chemical reaction or transfer of matter from one system to surrounding or vice versa then the system is said to be considered as chemical equilibrium. When there is no transfer of heat from one part to another when system and surrounding are distinguished by a diathermic wall (the wall which allows heat to flow) then the system is said to be in thermal equilibrium. A system will be in a state of thermodynamic equilibrium when it undergoes all there equilibriums.
