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

O Warmer sauce at the top of the pot is denser, so it sinks to the bottom of the pot, where it is warmed even mo

O The pot is only simmering, so there are no convection currents

Answer 1

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

This is because convection currents are created by differences in temperature, which cause materials to expand and become less dense, and rise. Cooler materials then flow in to replace them, creating a cycle of rising and sinking. In a simmering pot of spaghetti sauce, the heat is applied from the bottom, making the sauce at the bottom hotter and less dense, causing it to rise and circulate with cooler sauce sinking down to replace it. This creates a convection current which helps to evenly distribute the heat and flavors throughout the sauce.
