zeroth law
if A and B are in thermal equilibrium ,and B and C are in thermal equilibrium then A,B and C all are in thermal equilibrium
first law
let dq is heat given to system then ,this heat will enhance internal energy of system and system will do some work
dq = dU + dw
second law
entropy of universe is always increasing
integration( dq)/T = ds
where T is absolute temperature
and
ds is change in entropy
