ANSWER:
Step-by-step solution
Step 1 of 2
a)
Through the glass panes the heat is loss by the process of convection. The hot air being light rises up, and escapes through the edges.
Through the frame the heat loss is by the process of conduction. The metal frames being good conductors of heat conduct the heat to the outside.
Through the ventilation around edges cooling is by conduction and radiation.
