Answers are:
1) Photons are absorbed by hot gas atoms.
2) Energy is transferred through large-scale movement of material.
3) Energy is released into the photosphere.
The Sun interior is divided into three regions: the inner core, the radiative zone and the convection zone.
The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.
Radiative zone is around the inner core and in this area energy is transported by radiation.
The convection zone is the outer-most layer of the interior and in this area energy is transported by convection.
