<span>i think its decrease in density</span>
Gas<span> molecules </span>diffuse more<span> quickly </span>than<span> liquid and solid molecules </span>because<span> there is</span>more<span> free space between </span>gas<span> molecules, which gives them </span>more<span> room to move. This causes the molecules to bounce against each other and increases the rate of diffusion. The molecules in liquid are much closer together </span>than<span> those in </span>gas<span>.</span>
