Question

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot. What type of heat transfer is demonstrated by the sand in this example?

Answer 1

Answer: Conduction, because her feet are touching the hot sand.

Answer 2

Answer is: thermal conductuction.
Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.
The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.
