Question: How Can You Say One Substance Is Different From Other?

What is the basis of your classification?

Basis of Classification.

Species is the basic unit of classification.

Organisms that share many features in common and can breed with each other and produce fertile offspring are members of the same species.

Related species are grouped into a genus (plural- genera)..

What are four examples of properties?

physical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density.

How can matter of the same substance look so different?

The molecules of the substance remain the same no matter what state they are in. Matter looks different and behaves differently when it changes from one state to another. All particles of matter are in constant random motion. Particles of liquid water have less energy and move slower than particles of water vapor.

Why do we classify matter?

The temperature and pressure exerted on a sample of matter determines the resulting form of that the matter takes, whether solid, liquid, or gas. Since the properties of compounds and elements are uniform, they are classified as substances. When two or more substances are mixed together, the result is called a mixture.

What are the 22 states of matter?

Bose–Einstein condensate.Fermionic condensate.Degenerate matter.Quantum Hall.Rydberg matter.Rydberg polaron.Strange matter.Superfluid.More items…

What is a solid and liquid mixed together called?

The most common examples of dissolving involve a solid and a liquid, usually water. When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution.

Which terms are used to identify pure substances?

Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.

Why are substances different from each other?

Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.

Can a sample of matter exist in 2 states?

Matter takes many shapes, but most of us are familiar with the basic three states – solid, liquid, and gas. Now, for the first time, scientists have discovered that it’s possible for matter to exist in two of these states at once. … You have a chunk of potassium that is both solid and molten.

Are humans solid or liquid?

We are an amalgamation of solids and fluids, so not completely solid, no. We’re both liquids, solids and gases. Gas = nitrogen, oxygen, and carbon dioxide dissolved in various body fluids… Yes, we have hard parts and gelatinous parts; both are considered solid.

How do you categorize matter?

Matter can be classified into several categories. Two broad categories are mixtures and pure substances. A pure substance has a constant composition. All specimens of a pure substance have exactly the same makeup and properties.

How can you identify matter?

Some examples include:color.texture.boiling point.melting point.freezing point.density.taste.smell.More items…•

Can different substances have the same density?

Density is a characteristic property of a substance. … The mass of atoms, their size, and how they are arranged determine the density of a substance. 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 objects are matter?

Examples of MatterAn apple.A person.A table.Air.Water.A computer.Paper.Iron.More items…•

What Cannot be used to identify a type of matter?

Non- characteristic properties cannot be used to identify a substance while characteristic properties can be used for this purpose. b. What kind of property must mass be: characteristic or non-characteristic? Explain.

How many ways are there to classify matter list all of them?

The matter can be classified in two different ways; (a) according to its state, and (b) according to its composition. Matter can exist in three different states, solid, liquid, and gas, based on the way the atoms and molecules are arranged inside them. These three states are known as three different states of matter.

Why is it important to identify unknown substances?

Detecting known substances, and determining their quantity, is also important. … In manufacturing, it is important to detect any impurities in the product and to determine whether they are present in a significant amount. Analytical characterization is critical in pharmaceutical products, for instance.
