Problem
A glass window pane of thickness 5 mm separates the inside of a room at 30 °C from the outside air at 20 °C. The thermal conductivity of glass is 1.0 W m⁻¹ K⁻¹.
(a) Calculate the heat flux through the glass due to conduction.
(b) Name the principal mode by which heat is removed from the outer surface of the glass to the surrounding air.
