This is a complicated question because, on the one hand, it seems like they probably are additive – after all, a pure substance is just a single chemical element or compound, so it stands to reason that adding more of the same thing would just give you a larger total amount. However, there are also some reasons to think that they might not be additive. For example, it’s possible that the properties of a pure substance might change if you have a very large amount of it, or if you have a very small amount.
To really answer this question, we would need to know a lot more about pure substances and how they behave. Unfortunately, there isn’t a lot of information available on this topic. Nevertheless, we can try to piece together an answer from what we do know.
It seems likely that, in most cases, adding more of a pure substance will simply give you a larger total amount of that substance. However, there are some cases where this might not be true. For example, if you have a very large amount of a pure substance, the properties of that substance might change. For example, a gas might condense into a liquid, or a solid might melt. This is because the molecules of the substance are closer together, and they can interact with each other in different ways.
Similarly, if you have a very small amount of a pure substance, the properties of that substance might also change. This is because the molecules have a lot more space to move around, and they can interact with each other in different ways.
In conclusion, it’s difficult to say definitively whether or not volumes of pure substances are additive. This is because there is still much we do not know about pure substances and how they behave. However, in most cases, it seems likely that adding more of a pure substance will simply give you a larger total amount of that substance.
What is the difference between mass and weight?
Mass is a measure of how much matter is in an object, while weight is a measure of the force exerted by gravity on an object. An object with a large mass will have a large weight, but an object with a small mass can have a large weight if it is in a high gravity environment.
Frequently Asked Questions
What is the difference between a substance and a mixture?
A substance is pure, while a mixture is impure.
What is the difference between pure substances and compounds?
Pure substances are made of only one form of matter, while a substance is a mixture if it contains two or more forms of matter. A pure substance generally has a specific odor, taste, and color, while a compound can have different flavors, colors, and smells.
Which of the following is an example of a pure substance?
Sodium chloride Which of the following is an example of a mixture? Salt and water
Is water a solid or a mixture?
IN GENERAL, WATER IS A LIQUID UNDER NORMAL CONDITIONS BUT PHASE TRANSFER OCCURS WHEN TEMPERATURE AND PRESSURE ARE VARIED. PURE METALS SUCH AS GOLD, SILVER, AND PLATINUM ARE GOOD EXAMPLES FOR PURE SOLIDS.
What is the difference between pure substances and mixtures?
Pure substances are made up of only one kind of matter, while mixtures are combinations of two or more pure substances. A mixture can have varying physical and chemical properties, which is why boiling point and melting point can be different for mixtures.
