Why does the resistance of conductor rise with temperature?
as the temperature rises,the drift velocity increases hence relaxation time decreases and resistance increases.
What is the effect on the drift velocity of free electrons by decreasing the length and the temperature of wire?
As we know , resistance(R) is directly proportional to length(L) of conductor and resistence(R) is inversely proportional to current (I) and I=nAqv (v is drift velocity) So , if we decrease the length of the conductor , resistance of the conductor will decrease and current(I) will increase and drift velocity of free electrons will increase . And as we know resistance and temperature have direct relation so , by decreasing the temperature resistence will decrease and current will increase . So drift velocity will increase .
Why the magnitude of drift velocity is so small?

Does drift velocity of electron depend on diameter of conductor?
no

east
Drift velocity in two-phase flow?
it is the relative velocity of two phase that is gas and liquid.
What are Drift velocity and momentum relaxation time?
Drift velocity refers to a particle's average velocity being influenced by its electric field. Momentum relaxation time is the time required for the inertial momentum of a particle to become negligible.
