Ch 17.1 Energy, Heat, Work

QuestionAnswer
energy stored in chemical bonds of a substance chemical potential energy
symbol is q ; transfer of energy due to temperature differences heat
SI unit for energy Joules (J)
Chemical reaction that releases energy (loses heat) exothermic
study of energy changes during a chemical reaction thermochemistry
amount of heat needed to raise temperature of 1 gram of a substance 1 degree Celsius specific heat
non-SI unit for energy Calories (C)
Chemical reaction that absorbs energy (gains heat) endothermic
amount of heat needed to raise temperature of substance 1 degree Celsius (depends on mass & chemical compound) heat capacity
this lowers the activation energy of a chemical reaction catalyst
states that the energy in the universe is constant 1st law of thermodynamics
states that energy is not created or destroyed in a chemical or physical process law of conservation of energy
states that the heat of reaction can be found by adding thermochemical equations Hess's law
temperature scale used in heat calculations Celsius
