A bomb calorimeter determines calorific value by burning the fuel

  • A.in air at atmospheric pressure in an open crucible
  • B.in a steady stream past a water-cooled jacket
  • C.without any oxidant, measuring the decomposition heat
  • D.in oxygen at high pressure in a closed vessel

Answer: D

Complete combustion is assured by the excess of compressed oxygen, and the heat is measured from the rise in temperature of a known mass of water. The water formed condenses in the bomb, so the result is the gross value.
