CHEMISTRY FACTS

Chemistry
is a fascinating
science, full of
unusual trivia!
Here are some
fun <strong>and</strong>
interesting
chemistry <strong>facts</strong>
for you.

The only
elements that are
liquid at room
temperature are
bromine <strong>and</strong>
mercury.
However, you can
melt gallium by
holding a lump in
the warmth of
your h<strong>and</strong>.

If you pour a
h<strong>and</strong>ful of salt
into a full glass
of water, the
water level will
actually go down
rather than
overflowing the
glas

There is about
1/2 lb or 250 g of
salt (NaCl) in the
average adult
human body.

A pure element
can take many
forms. For
example,
diamond <strong>and</strong>
graphite both are
forms of pure
carbon.

The human body
contains enough
carbon to provide
'lead' (which is
really graphite)
for about 9,000
pencils.

One bucket full

Unlike many
substances,
water exp<strong>and</strong>s as

Lightning strikes
produce O3,
which is ozone,
<strong>and</strong> strengthen
the ozone layer
of the
atmosphere.

If you mix half a
liter of alcohol
with half a liter
of water, the
volume of the
mixture will be
less than one
liter.

Under certain
conditions, hot
water will freeze
more quickly
than cold water.
