Why does resistivity increase with temperature in metals?

we have formula

resistivity=m/ne^T

where m= mass of electron

n=number density of electrons

e=charge of electron

T=relaxation time

we know that as temperature increases relaxation time decreases

hence relaxation time is inversely proportional to both temperature as well as resistivity

as a result resistivity and temperature becom directly proportional hence resistivity increases with teamperature
