GENERAL KNOWLEDGE - CHEMISTRY 1

The follow are some example of physical properies of matter, except;

A homogeneous mixture of two or more substance.

These are properties that do depend on the amount of matter present.

Temperature in gaseous state

Liquid turns into solid

Density is equal to the mass divided by the volume.

A material's ability to undergo significant plastic deformation before fracturing

Volume is equal to length times width times hight.

Particles of matter are always moving or in motion

When an atom loses electron, it becomes a positively charge ion (cation)

It describes how much a substance's volume changes in response to changes in pressure.

Bose-Einstein condensate's temperature

Particles in the water are not attracted to each other, and will normally form into gas state

An act of mentally making groups based on similar properties

Solid turns into Gas

During chemical change, composition remains the same.

It measures how easily a material or object can bend, twist, or deform under the application of external force.

Solid turns into Liquid

A phenomenon where liquids spontaneously rise or fall in narrow spaces or tubes, against the force of gravity.

Historically, the distinction of matter is based on qualitative differences in properties.

It is a variant of an element that has the same number of protons in the nucleus but differs in the number of neutrons.

It is the central core of an atom which composed of protons and neutrons.

Gas turns into Liquid

Precision is independent of accuracy

Properties of matter that can be measured or observed without matter changing to a different substance.

Liquid turns into Gas

Is the product of reaction between an acid and a base ( other than water)

The external form or appearance of matter.

The compressibility of solid is generally lower than the compressibility of liquids and gases

It relates to heat or temperature

Physical change occur when;

A combination of two or more substances in which the substances retain their identity.

It is a way of expressing the precision or certainty of a measured or calculated value.

the process of particles, molecules, or substances spreading out and moving from an area of higher concentration.

When adding or subtracting, match the decimal places to the measurement with the fewest decimals for the result.

The ability of matter to spread out or transmitted to.

It maintains a fixed volume and shape composed of particles (atoms, molecules, ions) close together in a fixed place.

It has both volume and shape adapting to fit its container. The particles are chaotic, means they move without order.

these are substances that are made of only one type of particle

The capacity of matter to be flattened or reduced in size by pressure.

It has volume and shape, but as well as neutral atom. It contains Ions and electron which can move freely.

Temperature in Solid State

It is a process by which particles escape from the surface of a non-boiling liquid and enter the gas state.

The composition of mixture, after sufficient stirring, is the same throughout he solution.

Element that are good conductor of heat and electricity and have the tendency to form positive ions in ionic compound.

Temperature in plasma state

Compounds that contain carbon, usually in combination of elements such as hydrogen, oxygen, nitrogen and sulfor.

Final zero or trailing zeros to the last of non-zero digit in the decimal portion only are significant.

It describe how the composition of a substance change or does not change when it interacts with other substance/energy.

It has volume and shape that varies to its container. Also, it can move freely despite of being close to each other.

substance that yields hydrogen ions when dissolved in water.

Condensation of water vapor happens when the water vapor in air comes in contact with a cool surface.

Temperature in Liquid State

heterogeneous mixture in which relatively large particles scattered through solid, liquid, and gas.

the ability of a substance to be deformed or shaped through mechanical process without breaking or fracturing.

Weight, Volume, Length, width, Mass, Surface Area are extensive properties.

The ability of a substance to return to its original shape or size after being subjected to a deforming force.

When an atom gains electron, it becomes a negatively charge ion (anion)

When multiplying/dividing, the decimal places should be equal to the lowest number of significant figure.

Anything that occupies space and has mass.

Compounds other than organic compounds

Color,Odor,Taste,Luster,Malleability, Ductility, Conductivity, Hardness, B&M/F point, Density are Intensive properties.

When water vapor condenses in the air it is visible as tiny water droplets.

it is a measure of the accuracy of a position estimation system at a specific point in space.

Substance that contains at least one oxygen atom and one other element in its chemical formula.

The amount of space that matter occupies.

Physical properties of matter are categorized as either intensive or extensive.

It is referred to us the study of matter

It describes the tendency of a substance to fracture or break without significant plastic deformation or warning.

it refers to the closeness of a measured value to a standard or known value.

Any zeros between two significant digits are important.

It represent the number of protons in the nucleus of an atom and is represented by letter Z

Any salt that doesn't contain any formula.

Changes that do alter the identity of a substance, also called chemical reaction.

These are properties that do not depend on the amount of matter present.

What is the fourth state of matter

Terms used to describe chemical properties are "reactive", "inert", "unstable", and "combustible".

substance composed of atoms of two or more elements chemically united in fixed proportions.

Gas turns into Solid

a form of matter that has a definite or constant composition.

substance that yield hydroxide ions when dissolved in water.

A physical property of fluids (liquids and gases) that describes their resistance to flow or deformation.

a dispersion of particles of one substance throughout a dispersing medium made of another substance.

The degree of compactness of matter.

Element that usually poor conductor of heat and electricity.

It is anything that occupy space and has volume

it refers to the closeness of two or more measurements to each other.

In chemistry, symbol is a code for chemical element and normally consist of one or two letters.

substance that cannot be separated into simpler substances by chemical means.

The individual component of a mixture remain physically separated and can be seen as separate components.

It is the total number of protons and neutrons in an atomic nucleus and is represented by letter A

Non-zero digits are always significant
