Suppose a mixture contains two isotopes of fictitious element "A" shown below. 45 A 45 A and 46 A 46 A In the mixture 33% are 45 A 45 A and 67% are 46 A 46 A . What is the relative atomic mass for element "A"? Show your work below.

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.
