Of course.- You can have 1 cup of Water, 1 cup of Gasoline, and 1 cup of Molasses; Same volume, different densities.
They have different densities.
A spoon is a measure of volume. Different substances have different densities so that the same volume of two substances can have very different masses.
No
No. Solids made of different substances will normally have different densities.
Yes. A good example would be styrofoam and steel. The same volume of each of these substances would make for vastly different weights.
You are comparing their densities. Density is a measure of how much mass is present in a given volume. By comparing the masses of the same volume of different substances, you can determine which substance is more or less dense than the others.
First of all, there's no such thing as the mass of a substance, or the volume of a substance. You can have 0.01 kilogram of water or 10,000 kilograms of water. It only depends on how much you decide to scoop out of the bucket. The water itself has no characteristic mass. Similarly, you can have 1 milliliter or 1 cubic kilometer of potato salad. It only depends on how much you buy at the deli. The potato salad itself has no characteristic volume. If you measure out the same mass of two different substances, then the sample of the substance with the greater density will have less volume. If you measure out the same volume of two different substances, then the sample of the substance with the greater density will have more mass.
Mass can be used to distinguish between equal volumes of two substances because mass is a measure of the amount of matter in an object, while volume measures the space it occupies. Different substances have different densities, which is the ratio of mass to volume. Therefore, if two substances have the same volume but different masses, their densities will differ, allowing for distinction. This property is particularly useful in identifying substances and determining their purity.
Take three identical bottles. Fill one with air, one with water, and one with stones. The volumes of all three bottles are the same, but their weights are different, because they contain different masses. Different substances can easily have different masses in the same volume. That's why the concept of "density" is so useful.
Yes many different shapes can have the same volume
Depending up on the variable amount of different substances in the mixtures these can be different.
Yes, volume is an unreliable measure of the quantity of matter as the same material can have different densities, but the same volume. For example, 1L of ice, water, and steam all contain the same volume of water, but the number of atoms in that volume can vary.
