Question

why does a hot liquid move fast than cold liquid

Answer 1

hey frnd...
here's ur answer..
These molecules in liquid have some kinetic energies because they movewith some velocities … Hot water generally have fast movingmolecules because the heat makes the velocity of molecules increase… ... The conclusion is that hotwater moves fastbecause it has higher kinetic energy that of K.E of cold water…
hope it helps u..

Answer 2

because viscosity of liquid decreases with increasing temperature
