12. If all the undissolved KHT was not filtered out from the solution prior to titrating, would the calculated molar solubility of KHT be greater or less than the actual molar solubility? Explain.

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.

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
