Answer 2

The water in a lake is warmer on top than the water at the bottom of the lake due to the convection, so option(D) is the correct option.

• convection suggests warmer fluid molecules float to the height because the warmer fluid expands and decreases its density.
• Convection is the single or multiphase fluid flow that happens spontaneously due to the collective effects of material property heterogeneity and body forces on a fluid, most naturally density and gravity.
