Heat Capacity | Q = m c ΔT Q = Heat needed to change the object's temperature by ΔT (in J or Cal) Note that since ΔT measures relative temperature, which is the same in °C and °K. | |
---|---|---|

Specific Heat (c) | J kg^{-1} C^{-1} | The specific heat c is a unique property of a given material. It represents the amount of heat needed to change 1 kilogram of a substance from 14.5°C to 15.5°C. While its units are officially J kg^{-1} C^{-1}, also often used are kcal kg^{-1} C^{-1} |

Phase Changes | If a substance undergoes a phase change (for example, a cube of ice melts when placed in a cup of water) then the two phases m c Q = m L Q = Amount of heat needed to change the phase of the object (in J or Cal) | |

Latent Heat (L) | J kg^{-1} C^{-1} | The latent heat L of a substance refers to the amount of energy ttransfer in its phase change; this is in addition to the heat normally involved in cooling or heating the substance. |
