Question

Why is the concept of thermal equilibrium essential to the Zeroth Law of Thermodynamics?

Options

Choose one · Correct answer highlighted

It ensures heat flow It defines temperature equality Correct It measures work done It prevents energy conservation

Explanation

The Zeroth Law relies on thermal equilibrium, where no net heat flows between systems in contact, establishing that systems sharing this property with a third system have a common property—temperature—thus defining temperature measurement.
