 Okay. Let's try this one now. Label the following as extensive or intensive properties. So this is back in chapter one stuff. What I want you to remember is that extensive properties are found when you increase the amount of the substance. Does the property change? That's what an extensive property means. It's dependent on the amount of the substance. If I have a lot of it or a little of it, is that property going to change? Intensive means that no matter how much of the stuff you've got, that property stays the same. There's an inherent difference. So if you look at these different properties, you can see that some of them are what we call quantity-dependent, and some of them are quantity-independent. Okay? So again, extensive means quantity- dependent. Intensive means quantity-independent. So if we look at volume, we ask ourselves is that an extensive or intensive property? Well, isn't quantity-dependent? Does the volume get bigger or smaller depending on the amount of substance that you have? And yes, it does. So that would be an extensive property. The temperature of a substance change if you have a lot of it or a little of it? It's kind of a weird one, but no, it doesn't change. No, it doesn't smell of something. Change the smell. You might smell more of it or you might smell it at a higher concentration if there's more of it, but the odor inherently doesn't change. It smells the same whether you've got a little bit or a lot of it. So that also is an intensive property. Okay? The melting point, that also is an intensive property because it doesn't change whether you've got a lot of it or a little of it. Does, you know, four ice cubes melt at the same melting point that one ice cube does? Yes, they do. So this is also an intensive property. And lastly, color. Does color change if you've got a lot of it or a little of it? No. Okay? So that's also an intensive property.
