a. Zeroth law of thermodynamics
b. First law of thermodynamics
c. Second law of thermodynamics
d. none of the above
ANSWER: Zeroth law of thermodynamics
When a body A is in thermal equilibrium with a body B, And also the same body A is in thermal equilibrium with a body C, then body B and body C are also in thermal equilibrium with each other. This is called as Zeroth Law of Thermodynamics. It is the basis of temperature measurement.
