QUESTIONS WITH CORRECT ANSWERS 2026
Matter - CORRECT ANSWER -Anything that has mass and occupies space.
Mass - CORRECT ANSWER -The property that defines the quantity of matter in an object.
Chemistry - CORRECT ANSWER -
The study of the composition, structure, and properties of matter and of the energy consu
med or given off when matter undergoes a change.
Solid - CORRECT ANSWER -A form of matter that has a definite shape and form.
Liquid - CORRECT ANSWER -
A form of matter that occupies a definite volume but flows to assume the shape of its con
tainers.
Gas - CORRECT ANSWER -
A form of matter that has neither definite volume nor shape, and that expands to fill its co
ntainer; also called vapor.
Atom - CORRECT ANSWER -
The smallest particle of an element that retains the chemical characteristics of the element.
Molecule - CORRECT ANSWER -A collection of atoms chemically bonded together.
Chemical Bond - CORRECT ANSWER -
A force that holds two atoms in a molecule or a compound together.
Sublimation - CORRECT ANSWER -Transformation of a solid directly into a gas (vapor).
,Deposition - CORRECT ANSWER -Transformation of a gas (vapor) directly into a solid.
Energy - CORRECT ANSWER -The ability to do work.
Work - CORRECT ANSWER -
The energy required to move an object through a given distance.
Heat - CORRECT ANSWER -
A flow of energy from one object or place to another due to differences in the temperatur
es of the objects or places.
Chemical Reaction - CORRECT ANSWER -
The conversion of one or more substances into one or more different substances.
Potential Energy - CORRECT ANSWER -
The energy stored in an object because of its position or composition.
Kinetic Energy - CORRECT ANSWER -
The energy of an object in motion due to its mass (m) and its speed (u): KE=1/2mu^2
Law of Conservation of Energy - CORRECT ANSWER -
The principle that energy cannot be created nor destroyed, but can be changed from one f
orm to another.
Pure Substance - CORRECT ANSWER -
Matter that cannot be separated into simpler matter by a physical process.
,Physical Process - CORRECT ANSWER -
A transformation of a sample of matter, such as a change in its physical state, that does no
t alter the chemical identity of any substance in the sample.
Element - CORRECT ANSWER -
A pure substance that cannot be separated into simpler substances by any chemical proces
s. There are 118 elements and 90 are naturally occurring.
Compound - CORRECT ANSWER -
A pure substance that is composed of two or more elements linked together in fixed propo
rtions and that can be broken down into those elements by some chemical process.
Chemical Formula - CORRECT ANSWER -
A notation for representing the elemental composition of a pure substance using the symb
ols of the elements; subscripts indicate the relative number of atoms of each element in th
e substance.
Law of Constant Composition (Law of Definite Proportions)(Joseph Proust) -
CORRECT ANSWER -
The principle that all samples of a particular compound always contain the same elements
combined in the same proportions.
Mixture - CORRECT ANSWER -
A combination of pure substances in variable proportions in which the individual retain thei
r chemical identities and can be separated from one another by a physical process.
Homogenous Mixture - CORRECT ANSWER -
A mixture in which the components are distributed uniformly throughout and have no visib
le boundaries or regions.
, Solution - CORRECT ANSWER -
Another name for homogenous mixture. Solutions are often liquids, but they also may be s
olids or gases.
Heterogenous Mixture - CORRECT ANSWER -
A mixture in which the components are not distributed uniformly, so that the mixture cont
ains distinct regions of different compositions.
Immiscible Liquids - CORRECT ANSWER -
Combination of liquids that are incapable of mixing with, or dissolving in, each other.
Distillation - CORRECT ANSWER -
A process using evaporation and condensation to separate a mixture of substances with diff
erent volatilities.
Volatility - CORRECT ANSWER -A measure of how readily a substance vaporizes.
Filtration - CORRECT ANSWER -
A process for separating solid particles from a liquid or gaseous sample by passing the sam
ple through a porous material that retains the solid particles.
Chromatography - CORRECT ANSWER -
A process involving stationary and mobile phases for separating a mixture of substance bas
ed on their different affinities for the two types of phases.
Intensive Property - CORRECT ANSWER -
A property that is independent of the amount of substance present.
Extensive Property - CORRECT ANSWER -
A property that varies with the amount of substance present.
