Heat transfer is the gain or loss of heat by an object by heat conduction. The hot gas in disk shape cools faster because of increased surface area. Thus, option d is correct.

What is heat conduction?

Heat conduction is the thermal transportation of the heat from one substance to another by the virtue of the collision and the kinetic energy possessed by the particles of matter.

The rate of heat conduction has been directly proportional to the surface area. A contracting hot ball has a small area, whereas, a disk has a greater surface area and will cool faster.

Therefore, option d. the increased surface area cools faster.
