    It should be less than 1, dear Sourav.

    most probable speed is attained by the maximum number of molecules... however, it can't be 1 or more than 1 for obvious reasons, buddy! 😊 Not all molecules travel with the most probable speed!

    how sir

    eduncle-logo-app

    ok got it

    eduncle-logo-app

    Did you get it or you want me to explain again? 😊

    eduncle-logo-app

    so fractions of all molecules with different type of velocity will be less than 1?

    eduncle-logo-app

    Yes, all the speeds... whether be it most probable, average or root mean square...the fraction of molecules having this speed will always be less than 1. But, the fraction of molecules having most probable speed is highest, Sourav.

    That's why they are called most probable speed. 😊
