Can two objects of the same material have different densities?

Can two objects of the same material have different densities?

The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). The mass of atoms, their size, and how they are arranged determine the density of a substance. Objects with the same volume but different mass have different densities.

Can the same material have different volumes?

Mass and volume are physical properties of matter and may vary with different objects. For example, it is possible for two pieces of metal to be made out of the same material yet for one piece to be bigger than the other.

What are the factors that affect density?

The factors that affect the density

• Atomic weight of the element or the molecular weight of the compound .
• The distance between atoms ( Interatomic distances ) or molecules ( Intermolecular spaces ) .

Which object could be made of the same substance?

Long answer: Density is generally regardless of how big or small a substance is and is neither dependant on its shape. A statue made of gold and a brick made of gold might have different masses and volume but they have same density. By universal definition, density of a substance is the mass per unit volume.

How can you use density to identify a material?

You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. Assume that you have to identify an unknown metal. You can determine the mass of the metal on a scale.

What are two factors that will affect density and how?

The density of an object or quantity of matter is its mass divided by its volume. This is usually measured under standard conditions for temperature and pressure: 0°C and 1 atmosphere of pressure. One factor affecting the density of a material is how concentrated the atoms are in a given volume.

Can a material be described in the same way?

We know that some materials can be described in the same way. We say that these materials have the same properties. We also know that many objects in our homes and at school are made from different materials. Be careful not to mix up the object with the material!

What kind of objects are made of different materials?

We also know that many objects in our homes and at school are made from different materials. Be careful not to mix up the object with the material! Bottles are objects. They can be made of plastic or glass. Plastic and glass are materials. Plastic bottles do not break if we drop them.

How are plastic and glass the same material?

We say that these materials have the same properties. We also know that many objects in our homes and at school are made from different materials. Be careful not to mix up the object with the material! Bottles are objects. They can be made of plastic or glass. Plastic and glass are materials.
