Extracted text: A furnace is constructed with (inside) 0.20 m of firebrick, 0.10 m of insulating brick (middle) and 0.20 m of building brick (outside). The furnace is at 1200K, while the ambient temperature is 330K. Which of the following is NOT true about convection: Convection is possible in all phases of matter Convection is the sum of advection and diffusion Convection is proportional to the heat transfer coefficient Convection is proportional to temperature difference Convection is governed by Newton's law of cooling-
