Brownian movement:

Under ultramicroscope, colloidal particles appear to be in a continuous zig-zag motion known as Brownian movement.

1. It is independent of the nature of colloids.

2. It depends on size of particle.

\mathrm{Mobility \propto \frac{1}{\text { Size of particle }}}

3. It depends on viscosity of the solution.
\mathrm{Mobility \propto \frac{1}{\text { Viscosity }}}

4. It depends on temperature.

\mathrm{Mobility \propto Temperature}

Hence option 4 is correct.
