Question

Warm and cool fluids rise.
Warm and cool fluids sink.
Warm fluid rises and cool fluid sinks.
Warm fluid sinks and cool fluid rises.

Answer 1

The correct description of the movement of a fluid during convection is: Warm fluid rises and cool fluid sinks.

In convection, warmer fluids become less dense and rise, while cooler fluids, being denser, sink. This process creates a circular motion known as a convection current.
