1.	To find the % of volatile matter in coal, it must be heated in the crucible at ______ temperature.(a) 5261^0C(b) 3281^0C(c) 825^0C+10^0C(d) 925^0C+20^0CThis question was posed to me in an interview for job.This intriguing question comes from Analysis of Coal and Selection in section Fuel Technologies of Applied Chemistry
Answer» Correct choice is (d) 925^0C+20^0C For explanation: The moisture free COAL is taken into a silica CRUCIBLE and again it is heated at the temperature 925^0C+20^0C for 7 minutes then it is FIRST COOLED in air and late in a dessicator.
