They're not. As you can see below, the picture shows first a solid, then a liquid then a gas. The molecules start off very dense. Then the liquid is less dense then the gas is the least dense.
Since there are many different gases each one has someting special.
Because density decreases with increasing temperature.
The same mass of a gas will occupy a very much larger volume. If the same units were used the density of gases would be a much smaller number.
The space between the molecules is different in each case.
true
Because of different densities (ex. water and oil)
The greatest density would be the bottom and the lowest density at the top, because the liquids have different densities.
Different liquids boil at different temperatures. When the boiling points (the temperature at which a liquid boils) are sufficiently different, boiling can be used to seperate the liquids
You could find the densities of the liquids, and perform other simple tests such as the odor, and if you still can tell them apart, test the solubility of sugar in each liquid.
true
certain molecules are more tightly packed than others
Because they aren't soluble in each other and have different densities.
true
Gases, liquids and solid all have different consistencies (densities). So the sound is changed
Because liquids are different substances or mixture of substances; each chemical compound (substance) has a specific density.
It floats in different levels because the two liquids are different. They're densities are different from one another.
Because of different densities (ex. water and oil)
The vast majority of liquids have different densities. The weight of a liquid depends on the force of gravity and the mass of the liquid. The mass of a liquid depends on the volume of liquid and the density of liquid. Therefore, the vast majority of liquids have different masses, densities and corresponding weights.
The liquid with the higher density will stay down while the one with the lower density will rise up, thus stratifying the liquids into different layers.
The layer of the Earth that has a liquid and solid layer is the core. The outer core is molten, while the inner core is a solid ball of iron.
They form individual layers depending on their densities...the liquids with lighter density floats on liquid with heavier density......
