which best describes convection? it relies on the collision of particles within or between substances. it occurs in solids, liquids, or gases that are heated. it results when portions of a liquid cool and rise. it is driven by temperature differences within a fluid.
Answer
Brief Explanations:
Convection is the transfer of heat by the movement of a fluid (liquid or gas). It occurs due to temperature - driven density differences in the fluid. The first option describes conduction. Convection doesn't occur in solids. In convection, warmer (less - dense) fluid rises and cooler (more - dense) fluid sinks.
Answer:
It is driven by temperature differences within a fluid.
