  • Energy
    capacity to do work and release heat
    known and characterized by its effects
    cannot be seen, touched, smelled, or weighed
  • Kinetic Energy
    associated with movements
    mechanical
    thermal
    electrical
    acoustic
  • Potential Energy
    results from an object's position or state
    chemical
    gravitational
    elastic
    electrostatic
  • 1 calorie
    heat required to raise the temperature of 1 g of water by 1 C
    1000 cal = 1 kilocalorie
    1 kcal = 1 Calorie (food calorie)
    1 cal = 4.184 J
  • Heat
    transferred from a body
    high temperature to lower temperature
  • Heat Flow
    transfer of heat
  • Thermochemistry
    study of heat change in chemical reactions
  • System
    part of the universe on which is attention is focused
  • Open System
    can lose or gain mass and energy to across the surroundings
  • Closed System
    can absorb or release energy but not mass across the surroundings
  • Isolated System
    cannot exchange matter or energy with their surroundings
    adiabatic system
  • Surroundings
    part of the universe that exchange energy with the system.
    rest of the universe
    in close contact with the system
  • State of the System
    composition (g)
    temperature
    pressure
  • Endothermic Process
    heat flows from the surroundings into the system
    system absorbs
    energy increases into the system
    energy decreases in the surroundings
    internal
  • Exothermic Process
    heat from the system to the surroundings
    system releases
    energy decreases in the system
    energy increases in the surrounding
    external
  • Thermodynamics
    scientific study of the interconversion of heat and other kinds of energy
  • Zeroth Law
    If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other
  • First Law
    law of conservation of energy
    Energy can neither be created nor destroyed; energy can only be transformed
  • Internal Energy
    contained within a system
    composed of kinetic and potential energy
  • Work done by the system
    negative
  • Work done on the system
    Positive
  • Heat absorbed by the system
    endothermic process
    positive
  • Heat released by the system
    exothermic process
    negative
  • Specific Heat
    one gram of the substance
  • Heat Capacity
    given quantity of a substance
  • Constant Volume Calorimetry
    combustion reaction
    bomb calorimeter
  • Constant Pressure Calorimetry
    non-combustion reaction
    coffee cup calorimeter
  • Spontaneous Reaction
    favors the formation of products
    ice cube that melts at room temperature
  • Non Spontaneous Energy
    does not favor the formation of products
    photosynthesis
  • More microstate
    Higher entropy
  • Fewer microstate
    lower entropy
  • Gibbs Free Energy

    available energy of a substance that can be used in a chemical equation
