temperature | A numerical scale for measuring "coldness" or "hotness". It is determined by applying the Zeroth Law of Thermodynamics, which allows the temperature of an object to determined by calibrating it with an object of known temperature. [C, K , F, R] | 1D8 | |
temperature | absolute | Absolute temperature is temperature measure in either the SI scale of Kelvin or the English scale of Rankine. Using the absolute temperature scale, the lowest theoretical temperature is 0 K and the lowest experimental temperature reached is 0.000000002 K . [K, R] | 1E10 |
temperature | critical | 2B6 | |
temperature | reduced | A dimensionless temperature used with the generalized compressibility charts and other EOS's. The Reduced Temperature Tr, is defined as the ratio of the absolute temperature of the system to the critical temperature of the species in the system. As the reduce temperature approaches one, the temperature of the system approaches the critical temperature. | 2E8 |

thermal conductivity | Defined by Fourier's Law. It is the proportionality constant between the conduction heat flux and the temperature gradient. It is a temperature dependant property of a material that indicates its ability to transfer heat by conduction. [W/(m*K)] | 4B16 , 17 | |
thermal efficiency | A measure of the performance of a power cycle or heat engine. Thermal Efficiency is the ratio of the work produced by the cycle to the heat transferred into the heat engine from the hot reservoir. | 4F6, 6B4, 6C4 , 5 | |
thermal efficiency | heat engine | A measure of the performance of a heat engine or power cycle. Thermal Efficiency is the ratio of the work produced by the cycle to the heat transferred into the heat engine from the hot reservoir. | 6G2 - 4 |

thermal reservoir | An object for which the temperature never changes regardless of how much heat is transferred to or from it. The closest approximations of true thermal reservoirs are the ocean or the Earth's atmosphere. For modest heat transfer rates, systems in which a phase change occurs can be considered to be thermal reservoirs because their temperature remains constant as heat is added or removed. | 4F4, 6B2, 6F4 | |

thermodynamic cycle | A series of processes in which the working fluid within the system is returned to its original state when the cycle has been completed. | 1D4, 4F1, 5C1 | |
thermodynamic Properties | Also known simply as properties. Any characteristic of a system is a property of the system. Thermodynamic properties generally relate to the pressure, volume, temperature or energy of a system. | 1C4 | |

torque | A force acting on a body that is applied at a distance from the axis of rotation results in a torque on that body. Torque is the product of the appled force and the perpendicular distance from the point at which the force is applied to the axis of rotation. t = F*r [N*m] | 4A22 | |
