Lamar Rosario · Answer 1

Method A is radiation and Method B is convection.

Explanation:

Radiation:

The radiations are basically electromagnetic radiation that does not required any medium to travel. They can travel not through air and solid material but can travel through vacuum.

Convection:

The convection is method of transfer of heat through liquid or gaseous medium.

Summary:

As in method one, there is no medium, so radiation can pass without medium As in method two, there is liquid or gases medium, so heat travel through this medium will be convection.
