3 10 (a) During the determination of the calorific value of a coal sample by Bomb's calorimeter following results were recorded : Weight of fuel burnt = 1.9 gm Water equivalent of calorimeter = 500 gm Weight of water taken in calorimeter = 2300 gm Initial temp. of water = 25.05 °C Final temp. of water = 29.23 °C Acid correction = 15 cal. Fuse wire correction = 7 cal. Thread correction = 5 cal. Cooling correction = 0.26 °C. If the fuel contains 7.5% of hydrogen, calculate the Gross & Net calorific value of the coal sample provided that the latent heat of steam condensed is 587 cal/gm. Page 1 of 2 10 OR (b) Discuss the preparation, properties, and uses of the polymer made by polymerizing styrene and acrylonitrile in the presence of butadiene. How can you justify that the resulting polymer is a copolymer and an addition polymer?
