In 2006, the UK four-finger Kit Kat contained 233 dietary calories (kcal) (975 kilojoules). First will come the energy values, in both kilocalories and kilojoules. Each three-gram stick contains 10 Calories (42 kilojoules). Trifluoroacetyl chloride's heat of vaporization is 20 kilojoules per mole at 65 btus per pound. With these constants, "Q" is given in kilojoules per kilogram. A Polly Waffle contains 970 kilojoules of energy, and a sugars content of over 50%. Sulfotep's flash point is and its enthalpy of vaporization is 59.4 kilojoules per mole. However, a militarily useful energy is achieved with as little as several kilojoules.
