Iron has a density of 7.87 g/cm^3. What volume would 12.5 g of iron occupy?

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

From the question

mass = 12.5 g

density = 7.87 g/cm³

We have

We have the final answer as

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.
