Bonding and intermolecular forces are like marriage and dating. Marriage is a tight bond that connects people in a relationship. This bond of marriage is supposed to be unbreakable and takes lots of energy to destroy. Likewise, dating is a relationship between two people that is strong, but it also can be broken. There is much commitment holding these two individuals, but they are connected nonetheless.
An example of a real-life chemical equilibrium is a mood ring. A mood ring is a ring that you can wear on your finger that changes color based on what "mood" you're in. What really happens in a mood ring is that the color of the chemical inside changes based on what your body temperature is. The ring is filled with thermotropic crystals that change position in line with temperature. As the crystal's molecular structure shifts to match a new equilibrium, the wavelength of the light produced changes to make a new color. Therefore, the stressor in this equilibrium is obviously temperature. Furthermore, since this is about structure, not equations than it is a little harder to determine side favorability, but it can be assumed that the reaction is favorable to the left/reactants since the ring shows more red and green colors while it is heated.
The metaphor is very easy to visualize and makes for a good example of the differences between bonds and IMFs. You could talk about how more different people take dating more seriously than others, and how this is similar to the varying degrees of polarizability in IMFs.
ReplyDeleteI like this metaphor because it does a great job demonstrating the differences in strength between marriage (bonds) and dating (IMFs). It clear that there are attractive forces in both examples, but the easily understandable difference the two relationships does a great job at demonstrating how difference the attractive forces really care in respect to strength.
ReplyDeleteThis metaphor works. It's harder for married people to break up than people who are just dating. A weakness in your metaphor is that IMFs are between different molecules whereas bonds are not. Your metaphor involved two individual which can be seen as two atoms and not seperate molecules
