Afurnace consists of a 100 cm thick brick wall chamber in which gaseous material is combusted. the air surrounding the furnace chamber is at ambient temperature (25°c) and circulates due to natural convection with a value of the convection coefficient at 15 w/(m2.k). assuming a thermal conductivity of 1 w/(m. k) for brick wall, which can be assumed a blackbody, calculate the of the furnace wall if the outer wall inner temperature of the furnace wall if the oute temperature reaches 80°c at steady-state.

19. at high pressures, how does the volume of a real gas compare with the volume of an ideal gas under the same conditions, and why? eman- it is much less because real gas partides are not moving. there is no difference because the gas laws are always obeyed. it is much less because at high pressures the temperature drops. it is much greater because real gas partides take up space.
