The zeroth law of thermodynamics pertains to what relational condition that may exist between two systems?
A)zero net forces
B)zero velocities
C)zero temperature
D)thermal equilibrium

Question

Quizplus · Accepted Answer

The zeroth law of thermodynamics states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. Therefore, the zeroth law pertains to the condition of thermal equilibrium between two systems. Choice A pertains to mechanics, choice B pertains to kinematics, and choice C is incorrect because there is no such thing as "zero temperature" - temperature is a continuous physical quantity.
