, Basic Concepts about Matter
Matter: Matter is any substance which has mass and occupies space. All physical
objects are composed of matter, in the form of atoms and molecules, which are in turn
composed of protons, neutrons, and electrons.
Energy: Comes in different forms - heat (thermal), light (radiant), mechanical,
electrical, chemical, and nuclear energy. Matter release or absorb energy during their
changes.
Identify the matter and energy:
What is matter or energy description below?
1g of sugar, (matter)
1g of sugar produces 200 Kcal, (energy)
1 mole of O2 gas occupies 22.4 L at STP (matter)
Physical States of Matter
Depending on the temperature matter exists in four different states or phases:
solid, liquid, gas and plasma.
Phase: Phases have distinct properties and are sometimes called states of matter:
gas, liquid, and solid.

1) Solid 2) Liquid 3) Gas 4) Plasma
A definite volume A definite volume, No definite volumeAll matter will break
or size and distinct but it takes the or shape down into nuclei and
shape shape of its electrons as
container temperature is
increased
Major physical characteristics that define each state are the kinetic energy, heat or
the temperature of the particles of mater, and the attractive forces between particles
of matter determine the physical characteristics of each state. Many common materials
can be seen in the various states of matter depending on temperature.
Question:
a) Solid has
A. a shape and fixed volume
B. no shape, but fixed volume
C. no shape and no fixed volume
D. shape, volume, and takes up space
b) Currently, scientists have proved the existence of how many states of
matter? 4 states.
Properties of Matter
Matter posses certain characteristic which we call their properties.
Extensive properties depend on the amount of matter.
Intensive properties do not depend on the amount of matter.
Physical properties involve only a change in physical state (a liquid to a solid) and
no change in the identity of substances (water and ice is same substance) making
the matter. Most physical changes are reversible.
Chemical properties involve a change in the identity of substance making the matter.
Chemical changes are non reversible.
Describe each of the following properties and either intensive(I) or extensive(E), and
physical (P) or chemical(C).
1) Mass E P 2) Density I P 3) Temperature I P 4) Length E P
5) Color I P 6) Reactivity I, C 7) Heat capacity E P 8) Volume E P
9) Malleability I P 10) Luster I P 11) Specific heat I P 12) Weight E P
