which best describes convection?\nit relies on the collision of particles within or between substances.\nit occurs in solids, liquids, or gases that are heated.\nit results when portions of a liquid cool and rise.\nit is driven by temperature differences within a fluid.
Answer
Brief Explanations:
Convection is the transfer of heat within a fluid (liquid or gas) due to the movement of its molecules caused by temperature differences. Warmer parts of the fluid rise and cooler parts sink, creating a circulation pattern. The first option describes conduction. Convection mainly occurs in fluids (not solids well - solids don't have free - moving molecules for this type of heat transfer). Portions of a liquid that heat up rise, not cool and rise.
Answer:
It is driven by temperature differences within a fluid.
