Thermodynamics Unit Wise Quiz for Teens

The zeroth law of thermodynamics states that if two bodies are in thermal equilibrium with a third body, then they are in thermal equilibrium with each other.

The first law of thermodynamics states that energy can change from one form to another, but the total amount of energy remains constant. Energy cannot be created or destroyed.

Thermal equilibrium is when two bodies are in contact with each other and there is no heat exchange between them, i.e., the net flow of heat is 0.

<p>The zeroth law of thermodynamics is related to thermal equilibrium as it states that if two bodies are in thermal equilibrium with a third body, then they are in thermal equilibrium with each other.</p> Signup and view all the answers

<p>Thermal equilibrium occurs when bodies are in contact with each other and there is no net heat exchange. The zeroth law of thermodynamics states that if body A is in thermal equilibrium with body B, and body A is also in thermal equilibrium with body C, then body B and body C will be in thermal equilibrium with each other.</p> Signup and view all the answers
