The temperature of an ideal gas in a sealed rigid 0.20-m3 container is reduced from 360 k to 270 k and the final pressure of the gas is 40 kpa how much work is done by the gas during this process? (r = 8.31 j/mol ? k)in an electric furnace used for refining steel, the temperature is monitored by measuring the radiant power emitted through a small hole in the wall of the furnace, of area 0.5 cm2. this hole acts like a perfect blackbody radiator having the same temperature as the interior of the furnace. if the temperature of the furnace (and therefore of the hole) is to be maintained at 1650
