The rate of diffusion of liquids is higher than that of solids because:
1
in the liquid state, particles only move freely and do not have greater space between each other
2
in the liquid state, particles move freely and have greater space between each other
3
in the liquid state, particles do not move freely, but have greater space between each other
4
in the liquid state, particles do not move freely and do not have greater space between each other
