London dispersion forces are (permanent, temporary) while dipole-dipole forces are (permanent, temporary)

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

that's what i got you can count the number of atoms

c. electrical charges of ionic bonds.
