Question

dec. 2 thermal energy day 1 notes practice
what is it called when no more heat energy is transferred between two objects?

options:
thermal fusion
thermal conduction
thermal equilibrium
thermal expansion

Explanation:

To solve this, we analyze each option:

• Thermal fusion: Relates to combining nuclei, not heat transfer equilibrium.
• Thermal conduction: Is a heat transfer method, not the state of no heat transfer.
• Thermal equilibrium: By definition, it's when two objects have the same temperature, so no net heat transfer occurs between them.
• Thermal expansion: Is about volume change with temperature, not heat transfer equilibrium.

Answer:

C. Thermal equilibrium
