Heat will continue to flow between two bodies until they have the same amount of _____.

The concept of heat flow between two bodies is fundamentally tied to the principle of thermodynamics that describes how heat energy moves from a hotter object to a cooler one until thermal equilibrium is reached. The correct answer focuses on the idea that heat transfer will persist until the two bodies have the same amount of thermal energy.

In this context, "thermal energy" encompasses both sensible heat and latent heat, but it is the total thermal energy that is relevant in determining when heat transfer ceases. Sensible heat refers specifically to the heat added or removed that causes a change in temperature, while latent heat pertains to heat absorbed or released during a phase change, with no temperature change.

Therefore, the most accurate term to indicate that heat will flow until both bodies have the same amount is "thermal energy." This reflects the overall energy state including both types of heat, which is essential for reaching a balanced state between the two bodies.
