Which state of matter is compressible?

Gas

atoms or molecules are separated by large distances and are free to move relative to one another

Gas Matter

Atoms or molecules do not have long-range order

Amorphous Solid

The flammability of gasoline is a

Chemical Property

Matter is neither created nor destroyed in a

Chemical Reaction

Matter undergoes a chemical change when it undergoes a

Chemical Reaction

is a pure substance composed of different atoms that are chemically united (bonded) in fixed definite proportions

Compounds

Atoms or molecules are arranged in geometric patterns with long-range, repeating order

Crystalline solid

A pure substance that cannot be broken down into simpler substances

Element

A pure substance may be either an

Element or Compound

The behavior of matter is driven by

Energy

True or False Mass is smooth and continuous?

False

A mixture may be either a

Homogenous or Heterogenous

the energy associated with its motion

Kinetic Energy

The total energy of a sample of matter is the sum of its

Kinetic Energy and Potential Energy

have a fixed volume because their atoms or molecules are in close contact.

Liquid

atoms or molecules are close to each other but are free to move around and by each other.

Liquid Matter

Two states of matter that assume the shape of their containers

Liquids, Gas

is composed of different substances that are not chemically united but simply mixed together

Mixture

is composed of two or more different types of atoms or molecules combined in variable proportions

Mixture

All known elements are listed in the

Periodic Table

State changes—transformations from one state of matter to another, such as from solid to liquid

Physical Change

The characteristic odor of gasoline is a

Physical Property

the energy associated with its position or composition

Potential Energy

The substances present after the change are called

Products

is composed of only one type of atom or molecule

Pure Substance

Matter may be a

Pure Substance or Mixture

When matter contains two types of atoms, it may be a

Pure Substance or Mixture

In a chemical reaction, the substances present before the chemical change are called

Reactants

have fixed volume and rigid shape

Solid

Atoms may vibrate or oscillate, but they do not move around each other

Solid Matter

atoms or molecules pack close to each other in fixed locations

Solid Matter

states of matter

Solid, liquid, gas

Matter can be classified according to its

States

The energy associated with the random motions of atoms and molecules in matter

Thermal Energy

Energy can be changed from one form to another. True or False

True

Energy can be transferred from one object to another. True or False

True

Energy cannot be created out of nothing, and it does not vanish into nothing. True or False

True

During physical and chemical changes, the total amount of matter remains constant True or False?

True or False

is defined as the result of a force acting on a distance

Work

Matter

is defined as anything that occupies space and has mass

Chemical Property

is one that a substance displays only through changing its composition

Physical Property

is one that a substance displays without changing its composition

Energy

is the capacity to do work

Physical Change

matter changes its appearance but not its composition

Chemical Change

matter does change its composition

Atoms

submicroscopic particles that are the fundamental building blocks of matter

law of conservation of energy

that energy is neither created nor destroyed

Product

the substances present after the change

Reactants

the substances present before the chemical change

Molecules

two or more atoms joined to one another in specific geometric arrangements
