Question

fill in the blank. convection works because ______ move around when there are differences in temperature. solids solids and fluids fluids

Explanation:

Convection is a heat transfer process that occurs in fluids (liquids and gases) due to the movement of the fluid itself. Solids transfer heat mainly through conduction (vibration of particles without bulk movement), and they don't move around in the way required for convection. So only fluids are involved in convection's bulk movement due to temperature differences.

Answer:

C. Fluids
