If the reverse process, freezing the water to ice, is to occur, the water has to lose that enthalpy. The energy E in kilojoules (kJ) is equal to 400 joules (J) divided by 1000: E (kJ) = 400J / 1000 = 0. 9478 BTU. Find out how to convert calories into kilojoules. 2. a. Joule to Kilojoule Conversion Example. 44 J/g-°C and the specific heat of water is 4. 05 kilojoules KJ is struggling with test taking in all content areas. when the answer is bigger than 1000 J. −5460 kJ · mol −1. Summary. Heat of vaporization of water is 40.
