A hot water bottle is placed inside an empty box. The walls of the box are initially at 17°C. The surface area of the bottle is 0.0024 m². If the surface temperature of the water bottle is 75°C and the emissivity of the bottle is 0.70, what is the initial rate of radiation heat transfer from the bottle to the walls?
