Why is density the same in every sample of a substance?
Why? The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is. All matter has its own unique density.
Do all substances have the same density?
Density is an intensive property. This means that regardless of the object’s shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density.
Does the density of a substance change with sample size?
Explanation: Density is an intensive property. This means that regardless of the object’s shape, size, or quantity, the density of that substance will always be the same.
Does the density of a substance depend on how much of it there is?
Because the density of a substance does not depend on the amount of substance present, density is an “intensive property”. To measure the density of a sample of material, both the mass and volume of the sample must be determined.
What is density in 6th grade words?
substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.
What is the difference between mass and volume?
Volume – How much space an object or substance takes up. Mass – Measurement of the amount of matter in an object or substance.
Are mass and volume directly related?
We can say that the volume of the object is directly proportional to its mass. As the volume increases the mass of the object increases in direct proportion.
What is the relationship between volume and mass of water?
Water molecules all have the same mass and size. Water molecules are also packed pretty close together. They are packed the same way throughout an entire sample of water. So, if a volume of water has a certain mass, twice the volume will have twice the mass, three times the volume has three times the mass, etc.
What is the difference between mass and weight and volume?
Mass is a measure of the matter within a body. Volume is the quantity of space a body occupies measured in liters and milliliters in the metric system and ounces and pounds in the English system. The same volume of two different substances, may have different weight and mass.
Does all matter have volume?
Matter is all the “stuff” that exists in the universe. It has both mass and volume. Volume measures the amount of space that a substance or an object takes up.
Does all matter have volume and mass?
Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object). There are four states of matter, solid, liquid, gas, and plasma. If something is in a solid state of matter, it has a definite shape and volume.
Does some matter have no volume?
Three states of matter exist—solid, liquid, and gas. Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Has definite volume and can flow?
SolidsEdit Because the particles don’t move, solids have a definite shape and volume, and can’t flow. Because the particles are already packed closely together, solids can’t easily be compressed. Because there are lots of particles in a small volume, solids are dense.
What state of matter can change both shape and volume?
Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.
