A | B |

Thermal Energy | the total potential and kinetic energy associated with the particles of a material |

Heat | thermal energy that is transfered from one object to another |

Temperature | the physical property that determines the direction in which heat energy will flow |

Kelvin | temperature scale based upon the absolute zero concept of energy |

Celsius | originally had zero degrees as the steam point not the ice point |

calorie | unit of thermal energy equivalent to 4.186 joules |

Coefficient of linear expansion | change in unit per unit length for a change in temperature of one degree |

Water | has 4 degrees Celsius as a point of maximum density |

Charle's Law | relates volume of a gas to its Kelvin temperature |

Boyle's Law | relates the volume of a gas to its pressure |

Universal Gas Constant | has a value of 8.21 x 10-2 L atm/mol K |

Heat capacity | quantity of heat needed to raise temperature 1 degree |

Specific heat | heat capacity per unit mass |

Endothermic | process which absorbs heat |

Exothermic | process which gives off heat |

Law of Heat Exchange | states that Q lost = Q gained |

Calorimeter | container to contain heat transfers |

Heat of Fusion | heat needed to melt a unit mass of a material at its normal melting point |

Heat of Vaporization | heat needed to vaporize a liquid at its normal boiling point |

Critical point | Upper limit of the triple point |
