Does everything have a different density?
The value of an object’s density depends on what it’s made of as well as its temperature; for example, lead weights are denser than feathers, and cold air is denser than hot air.
How do you compare different densities?
Doing the Math Density= mass/volume with the unit grams/mL. Measure the mass of the object that you are going to be using. To do this, lay it on a scientific scale and get the mass in grams. Measure the volume of the substance in milliliters.
How do you find out whether two objects have the same density or not?
Answer:Because mass and volume are independent, two objects with the same volume can have different masses. Therefore, the objects can have different densities. However, if two objects have the same mass and volume, they will have the same density.
How do you know if something has more density?
If we take the same volume (one cubic centimetre) of foam, wood and concrete, we can see that each has a different mass. If something is heavy for its size, it has a high density. If an object is light for its size it has a low density.
What are 3 facts about density?
An object with a density less than 1 gm/cm3 will float in water. High density materials such as metal, concrete, or glass, will sink in water because they are higher density than water. An object with a density greater than 1 gm/cm3 will sink in water. The density of water can be changed by the addition of minerals.
Why do different solids have different densities?
All types of matter—solids as well as liquids—are made up of many different atoms. Depending on the mass of these atoms, their size and the way they are arranged, different substances will have different densities.
How would you describe density?
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
Does less dense float or sink?
If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.
What does it mean when objects have the same density?
The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.
What if something has the same density?
If the object is of equal density it will sink into the water so that no part of the object is above the surface. It may or may not “float” just but entirely below the surface. As eigenperson said, if pushed down it might stay at the new depth but that’s tricky. If the object is of greater density it will sink.
What has a lot of density?
Solids
| Substance | Density(g/cm^3) |
|---|---|
| Platinum | 21.45 |
| Plutonium | 19.84 |
| Rubber | 1.506 |
| Silver | 10.49 |
Do you know about density?
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter). For example, sponges are low in density; they have a low mass per unit volume.
