Define Temperature | Temperature is the measure of hotness or coldness of a body |

What are the units of Temperature? | The SI unit of Temperature is the kelvin (K) |

What is Heat Capacity? | The Heat Capacity of an object is the heat energy needed to change its temperature by 1K (1 degree C) |

What is the formula for Heat Capacity? | Q = C X (change in temperature) |

Define 'Specific Heat Capacity' | The Specific Heat Capacity of a substance is the heat energy needed to change the temperature of one KG of that substance by one K (kelvin) |

What is the unit for Specific Heat Capacity? | Joule per KG per K ( J kg-1 K-1) |

Formula for Specific Heat Capacity | Heat (lost) OR (added) = Mass x Specific Heat Capacity x (rise) OR (fall) in temperature |
