Fuel Calculations Flashcards
chemical energy
energy stored in the bonds of chemical compounds
exothermic
A chemical reaction involving the release of energy in the form of heat
endothermic
A chemical reaction involving the absorption of energy in the form of heat from its environment
enthalpy
measurement of the internal energy of a system
complete combustion
reaction with oxygen to produce carbon dioxide and water
incomplete combustion
reaction with oxygen to produce carbon monoxide or solid carbon and water
energy profile diagram
representation of the energy transformed of a chemical reaction
activation energy
The minimum amount of energy required for a reaction to occur
heat of combustion
The amount of heat released by the complete combustion of a substance
specific heat capacity
The heat required to raise the temperature of 1gram of water by 1C
thermochemical equations
A balanced stoichiometric equation that includes the enthalpy change of the reaction
gas
A state of matter with no fixed shape or volume
ideal gas
A substance assumed to be composed of molecules of negligible volume with no intermolecular interactions
pressure
The force a gas exerts on the walls of its container
standard laboratory conditions (SLC)
25C, 100kPa
