Determine the mass of magnesium in a beaker if the mass of the beaker is 1.80 g and the mass of the magnesium and beaker is 2.85 g to two decimal places.

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.

imma come back to you hold on

im not exactly sure but i think its b!
