PHYSICAL CHANGES
size
shape
form
state
Which means the ingredients
keep
the same
chemical composition
CHEMICAL CHANGES
new
flavors
new
odors
Changes
to
food
during cooking occur
on a
molecular level
Many
chemical changes
in cooking make food
ENERGY
Is needed to
start reactions
by
breaking
molecular bonds
Accompany
chemical changes
activation energy
The
minium amount of energy required
for a chemicalr reaction to occurs
CHEMICAL
CHANGES
REACTIONS
Occur
when two or more
substances
or interact
reactants
As a result, the
molecules
of the reacting
substances
changes**
And change their
chemicals formulas
Chemical reactions
Take place when to or more
substances interact
chemical bonds
break
apart and
re-form
Break matter
combine matter
Not
all
chemical reactions
occur t the
same rate
The
speed
which
reactants
turn into
products
is known as the
reaction rate
