An example of the zeroth law of thermodynamics would be a) the efficiency of an engine can never reach 100%. b) all items in the freezer are at the same temperature as each other. c) a car converts chemical potential energy into heat and kinetic energy. d) it is impossible to reduce the temperature of a substance to absolute zero. submit

Answer;

B) All items in the freezer are at the same temperature as each other.

Explanation;According to the Zeroth Law of Thermodynamics, if two systems are each in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other.The zeroth law is important as it allows us to define the concept of a temperature scale.  Zeroth Law results from thermal equilibrium and allows a conclusion that temperature is a physical quantity. In our case, a good example will be the fact that All items in the freezer are at the same temperature as each other, as they are sharing the temperature provided by the refrigerator.

In the conservation of mass, mass (which is the same as energy) can never be created or destroyed in the same way oil is formed from the remains of small animals and plants that died and fell to the bottom of the sea and their mass (energy) is conserved as oil.
