Ch. 9 - Energy, Enthalpy, Thermochemistry
Energy- the capacity to do work (W) or produce heat (q)
Types
Potential = position or composition (bonds)
Kinetic = motion
Units
1 calorie = 4.184 J
1 L*atm = 101.3 J
****Temperature does NOT equal heat
Temperature measures hot/cold vs. Heat measures energy transfer between objects
First Law of Thermodynamics
Energy is conserved
Energy of universe (system+surroundings) is constant
