Question

In the convection process rate of heat transfer is compared in the option between gas and liquid, choose the correct statement

• A. Gas convects more as compared to other
• B. Liquid convects more as compared to other
• C. Liquid convects more as compared to other only if certain factors assists water
• D. None of the above

Answer 1

Answer: (C)

Liquid convects more as compared to other only if certain factors assists water

In liquids, particles are neither too close nor too far but comparatively closer than gas; so liquid convects more as compared to gas. At $0^{\circ }C$ and $4^{\circ }C$ when density is more; the rate of convection decreases. But when the density of water is normal i.e. at room temperature, the convection rate of water is pretty good. Density only affects the rate of convection.
