Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed.

Warmer sauce at the bottom of the pot is denser, so it rises, forcing cooler sauce down, where it is warmed.
Warmer sauce at the top of the pot is denser, so it sinks to the bottom of the pot, where it is warmed even more.

The correct answer is:

Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed.
