Document Summary

C12 thermal energy: key ideas. A truly isolated system has no transfer of energy to/from surroundings. A functionally isolated has no energy flows or external interacts that do work on the system. A momentarily isolated system can occur usually in a collision. Heat is a form of energy transfer, energy lost with sliding or friction is transformed to: key equations thermal energy. Kavg = = (cid:2871)(cid:2870)(cid:3029) (where kb = 1. 38 x 10-23) Joule experiment: h (height of mass) = (cid:3040)(cid:3298)(cid:3280)(cid:3004) (cid:3040)(cid:3298)(cid:3280) . C13 internal energy forms: key ideas. Negative u values mean energy is released. Latent energy transformation: for condensation or freezing, there is - uth, for vaporization/melting, there is + uth. Types of internal energy: rotational (urot), thermal (uth), latent (ula), chemical (uch), nuclear (unuc) Forms of energy transfer: work (w), heat (q), emr [eer], mechanical waves [emw]: key equations electrical current [eec], mass transfer [emt]
