This is due i will mark you as a brainliest if answered #1-7

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.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
