Explain effect of temperature on Maxwell Boltzman velocity distribution. |
Answer» Solution :Relation between molecular speed and number of molecular with increase in TEMPERATURE : Comparison of Low temperature `T_(1)` and high temperature GRAPH as under. According to Maxwell - Boltzman DISTRIBUTION curve at high temperature `T_(2)` curve is flat and wide that two Temperature curve. (i) Most probable speed of molecules increases with temperature and curve becomes more wide at high temperature `(T_(2))`. (ii) Wide curve indicated that number of molecules having more speed increases with temperature. (iii) Value of Average speed `(u_(AV))` increases at higher temperature `(T_(2))` than `(T_(1))` and most PROBABLY speed is low so, `u_(av)` and `u_(mp)` value is low at high temperature. `u_(av)` and `u_(mp)` value is high at low temperature. Number of molecules at high temperature `(n_(2))gt` number of molecules at lower temperature `(n_(1))`. |
