| 44 | 44 | Now, depending on the ratio of !Erad/Egas, can expect to get different rates at which the temperature will rise or fall due to the radiation (right?). While the coupling rate does tell us how fast tgas will approach trad, there is another factor involved which is how much relative energies these fields have. That is because each can act as a thermal bath for the other. The idea is that if the radiation has >>> energy than the gas, then it can quickly transfer heat into the gas (but note, the gas will not change the temperature of the radiation). However, if the gas >>> than the radiation, then the gas is a bath and the radiation will not change the temperature significantly. |
