A NASA satellite showed that in 2012 the ozone hole over Antarctica had a maximum surface of 21.9 million km^2. The largest ozone hole on record occurred in 2006 and had a surface area of 29.2 million km^2. Calculate the difference in diameter (in meters) between the ozone hole in 2012 and in 2006. (Assume ozone holes are circles).

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.

the answer is d.) potassium
