• QUESTION: What is the difference between an
exothermic reaction and an endothermic reaction?
• ANSWER: A chemical reaction that releases energy is
called an exothermic reaction. A chemical reaction
that stores energy is called an endothermic reaction.

KEY VOCAB 01: WORDS 1 AND 2
1. Heat (noun) Thermal energy that
is being transferred
from one place to
another.
2. Energy (noun)-
Exists in a variety of forms, such
as electrical, mechanical, chemical,
thermal, or nuclear, and can be
transformed from one form to
another. It is measured by the
amount of work done, usually in
joules or watts.

OBJECTIVES
• Be able to define and thoroughly explain the
law of conservation of energy in terms of
how energy changes form.
HEAT IS DIFFERENT THAN
THERMAL ENERGY.
• Heat is thermal energy that is being transferred from one
place to another.
• An object’s thermal energy equals the total energy of all
its moving particles.
• Heat transfer happens when some of this energy moves
from one object to another object.
ENERGY IS NEVER CREATED AND NEVER
DESTROYED; IT SIMPLY CHANGES FORM.

RULE ABOUT HEAT FLOW
• When objects of different temperatures are
in contact, heat always moves from the
warmer to the cooler object until their
temperatures are equal.
SPECIFIC HEAT
• Specific heat is the amount of heat needed to raise the
temperature of a mass by one degree.
• The specific heat of a substance is a physical property
dependent upon the molecular structure and phase of the
substance.
