What does the zeroth law of thermodynamics allow us to define?
a.
pressure
b.
work
c.
latent energy
d.
thermal energy
e.
temperature

The correct choice is D.  thermal energy

According to the zeroth law of thermodynamics, if two thermodynamic systems are each in thermal equilibrium with a third one, then they are in thermal equilibrium with each other. Accordingly, thermal equilibrium between systems is a transitive relation.Hence option D is the right answer
