in this video i'll talk about the jiroth law of thermodynamics and it's a pretty simple law of thermodynamics what is it so let's say we have three objects a object a object b and object c and object a and c are in thermal equilibrium what is the mean by thermal equilibrium so when i say thermal equilibrium a and c that means object a and c are at the same temperature or in other words when we place them in contact with each other physically contact then there is no exchange of heat energy between a and c and it happens only when both a and c are at the same temperature okay so coming back to again a and c are at the same or are in thermal equilibrium b and c are also in thermal equilibrium then the zeroth law of thermodynamics tell you that a and b must be in thermal equilibrium okay so mathematically if you have to write down is ta is equal to tc that means a and c are in thermal equilibrium and also b and c are in thermal equilibrium and this means t a and t b must be in thermal equilibrium if there is no exchange of heat energy between a and c if there is no exchange of heat energy between b and c then there should not be any exchange of heat energy between a and b that is the zeroth law of thermodynamics okay so this is it from this short video again if you have any questions write down your questions in the comment section below thank you very much
