LESSON 1 Flashcards
PHYSICAL PROPERTIES
are properties that do not depend on the amount of
matter present or being measured.
❖ If there is a change in the amount of matter, these properties will remain the
same. EX: Color, Hardness, and boiling point.
Intensive properties
are properties that depend on the amount of matter
present or being tested. If there is a change in the amount of matter, these
properties change too. EX: Volume, Mass, Length, and Shape
Extensive properties
helps determine how an element (especially a metal)
might be used. Many elements are fairly soft (silver and gold, for
example) while others (such as titanium, tungsten, and chromium)
are much harder.
Hardness
is an interesting example of hardness. In graphite, (the
“lead” found in pencils) the carbon is very soft, while the carbon in
a diamond is roughly seven times as hard.
CARBON
is the amount of mass given in a volume. (is a measure of the amount
of space occupied by matter)
DENSITY
Is the measure how much the substance
dissolves in a given volume of liquid.
SOLUBILITY
Pertains to how substances are attracted
to magnet. You can use magnets if you
want to pick up nails in a wood chip.
MAGNETIC PROPERTY
such as red, blue and yellow, is perceived in the eye receptors of the eyes, as they
interact with different spectra of light.
COLOR
Is the perceived smell of an object, identified by the olfactory receptors of human and animals.
ODOR
Is the sweetness, sourness, saltiness, bitterness, and umami flavor of food.
TASTE
Is the temperature where solid changes to liquid.
MELTING POINT
Is the temperature where liquid changes to gas.
BOILING POINT
Is a property of a material that pertains to the interaction of light on the surface of metals.
LUSTER
is the tendency of a metal to break even when a small amount of force is applied.
BRITTLENESS
Is the ability of metal to be hammered or shaped into thin sheets without breaking or cracking
MALLEABILITY
