Accronding to the Maxwell distribution of speeds of a collection
of molecules , the fraction of molecules with speeds between
u and u+du P(u) = A x u*2 x exp(-mu*2/2kT)du
where A is a constant . The Mexwell distribution of kinetic
energies, P(E)dE is _______________________
(a) (A/2) (2/m)*2/3 E*1/2 exp(-E/kT)dE
(b) A(2/m) E exp(-E/kT)dE
(c)AE*2 exp(-E/kT)dE
(d)(A/2) (2/m)*2/3 E*2 exp(-E/kT)dE
想請問大家 我只有學過分子速率的機率分布圖
那動能要怎麼做轉換阿 有人知道嗎 謝謝.......
