Why would it be more comfortable to walk on hot beach sand in flip-flops

than without them?

O A. Thermal insulation is blocked by the flip-flops.

B. Convection warming is blocked by the flip-flops.

C. Radiation warming is blocked by the flip-flops.

O D. Thermal conduction is blocked by the flip-flops.

D. Thermal conduction is blocked by the flip-flops.

Explanation:

Convection is a process of heat transfer which involves fluids (liquid or gas). This however rules convection out of the answer.

Radiation involves heat transfer from the sun to bodies on earth.

Conduction involves heat transfer between two solid bodies. Hot beach sand and flip-flops are solid bodies which validates thermal (heat) conduction.
