Calculate the pH of a 0.50 M solution of sodium benzoate (NaC6H5COO) given that the Ka of benzoic acid (C6H5COOH) is 6.50 x 10-5.

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.

how do models compare to real-world objects?

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

: )

they are made of gases.

they have a spherical shape.

they make energy through fusion.
