Does density change when the size of an object changes?
No. A drop of water and a tankerful of it have the same density. But these are two different masses of the same material. If you have, say a piece of metal and heat it up so that it expands, and there is still the same amount of substance, then the density decreases as the substance expands. Water expands as it freezes; that is why ice floats in water.
How does the density of a material change when the material expands?
When a material expands, its volume increases while its mass remains constant. This causes the density of the material to decrease because the same mass is now spread out over a larger volume, resulting in a lower density.
How does the density of galaxies change as the universe expands?
As the universe expands, the density of galaxies decreases. This is because the space between galaxies increases as the universe expands, leading to a lower concentration of galaxies in a given volume of space.
What happens to the density of a material when you change the size of that material?
Changing the size of a material does not affect its density. Density is a characteristic property of a material that remains the same regardless of its size or shape. Density is calculated by dividing the mass of a material by its volume.
When a solid block of materials is cut in half what happens to the density?
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.

How does density change as the universe expands?
The density of what? Any metal, liquid, etc. will have the same density since density depends on mass and volume of the sample (not volume of the universe).
How does the density of water change as it expands?
Since "expansion" in this case refers to the increased spacing between molecules, then the density must decrease.

What are the two physical properties that change with temperature?
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.
What is the relationship between phase diagrams and density in materials?
Phase diagrams and density in materials are related because the different phases of a material (such as solid, liquid, or gas) have different densities. The phase diagram shows how the phases of a material change with temperature and pressure, which can affect the density of the material. In general, as a material changes phase, its density can also change.
When a solid block of materials is cut in half what happens to the density?
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
What happens to an object's density when it heats up and expands?
The density decreases.
What are the three physical properties that vary with temperature?
Three physical properties that vary with temperature are volume, density, and thermal expansion coefficient. As temperature increases, volume generally expands, which can lead to a decrease in density. The thermal expansion coefficient quantifies how much a material expands or contracts with changes in temperature.
Why can't mass change density?
Mass doesn't change density because density is a qualitative property, meaning it is a quality for material's density, not a measure of how much density in the material. A quality is the same thing as a trait, for instance, pine trees have pine needles, even the little ones, it does not change because they are different sizes because it is a trait for a pine tree to have needles.
