Q2. Attempt any three questions- (5x3 =15)
(a) With the help of a neat diagram, explain the working and principle of Bomb calorimeter.
(b) A sample of coal contain C=89%, H=8% and ash=3%. The following data were obtained when the
above coal was tested in bomb calorimeter: Weight of coal burnt= 0.85 g; Weight of water taken= 850 g;
Water equivalent of bomb and calorimeter= 3500 g; Rise in temperature= 2.5˚C; Fuse wire correction =
