Unit3_Lesson5:Thermo
Thermo part 2, calorimetry, enthalpy, fusion/vaporization, Hess's Law
Question | Answer |
---|---|
calorimetry | the precise measurement of the heat flow out of a system |
enthalpy | the heat content of a system (H) |
molar heat of fusion | the heat absorbed by one mole of a solid substance as it melts to a liquid at a constant temperature |
molar heat of vaporization | the amount of heat necessary to vaporize 1 mole of a liquid |
Hess's Law | if you add 2 or more thermochemical equations to give a final equation, then you can also add the heats of reaction to give the final heat of the reaction |
thermochemical equation | a chemical equation that includes the enthalpy change |
standard heat of formation | the enthalpy change that accompanies the formation of 1 mole of a compound from its elements in their standard states |
