Chemistry.
The study of composition, structure, properties, a d transformation of matter is a branch
of science known as _________
matter
is anything that has mass and occupies space.
matter
It is the physical substance of the universe, making up everything we encounter in our
daily lives.
matter
The study of it is a fundamental concept in physics and chemistry, helping us
understand the composition and behavior of substances in the natural world.
matter
can exist in various states, which are commonly categorized into three primary forms:
solids, liquids, and gases.
Solid, Liquid and gas
Matter exist in three phases
Solid
Particles are tightly packed with ordered arrangement.
Solid and Liquid
Particles are close to one another.
Solid
Particles are essentially in fixed position.
Solid
Rigid or inelastic particles locked into place/do not move from one place to another
Solid
Particles are difficult to compress/not easily compressible.
Solid
Very minimal space between particles
Solid
Particles do not flow easily
Solid
The rigid particles do not move nor slide one another
Solid
has definite/fixed volume and shape.
Solid
does not conform to the shape of it's container/retains own shape
Liquid
Particles are loosely packed with no regular arrangement/ Particles have a disordered
arrangement.
Liquid
Particles are easy to compress.
, Liquid and Gas
Particles are free to move, relative to other particles.
Liquid
Very small spaces between particles
Liquid
Particles have the ability to flow
Liquid
The particles move or flow past one another
Liquid and Gas
No definite shape, assumes the shape of the container.
Liquid and Gas
can move/slide past each other
Liquid and Gas
Assumes the shape of the container
Gas
Particles have a total disordered arrangement/widely separated
Gas
Particles are far apart
Gas and Liquid
Particles have complete freedom of motion
Gas
Can move at very high speed last one another
Gas
Particles are highly compressible
Gas
Large space between particles.
Gas
Particles move/flow easily at high speed
Gas
The particles move apart one another
atoms
Matter is composed of tiny particles called _____, which combine to form molecules.
These _____ and molecules interact with each other through various forces, leading to
the diverse properties and behaviors of different types of matter.
Atom
Is the smallest particle of an element
Atoms
are the basic building blocks of matter.
Atoms
They are the smallest units of an element that retain the chemical properties of that
element.
Atoms
consist of a central nucleus, which contains positively charged protons and uncharged
neutrons, surrounded by negatively charged electrons orbiting in specific energy levels
or shells.
