|
the ability to burn.
|
|
Reactivity
|
when 2 substances get together something can happen.

|
inability to burn.
|
|
Density
|
amount of matter in a given space. Mass per unit volume.
|
|
Physical change
|
a change that affects one or more physical properties of a substance; many physical changes are easy to undo.
|
|
Chemical change
|
a change that occurs when one or more substance are changed into entirely new substances with different properties; cannot be reversed using physical means.
|
|
Matter
|
anything that has volume and mass.
|
|
Mass
|
the amount of matter that something is made of.
|
|
Volume
|
the amount of space that something occupies or the amount
of space that something contains. |
|
Meniscus
|
the curve at a liquid’s surface by which you measure the
volume of the liquid. |
|
Gravity
|
the force of attraction between objects that is due to their
masses. |
|
Weight
|
a measure of the gravitational force exerted on an object,
usually by the Earth. |
|
Newton
|
the SI unit of force.
|
|
Inertia
|
the tendency of all objects to resist any change in motion.
|
|
Change of State
|
the conversion of a substance from one physical form to
another |
|
Melting
|
the change of state from a solid to a liquid.
|
|
Freezing
|
the change of state from a liquid to a solid.
|
|
Vaporization
|
the change of state from a liquid to a gas; includes boiling and
evaporation. |
|
Boiling
|
vaporization that occurs throughout a liquid.
|
|
Evaporation
|
vaporization that occurs at the surface of a liquid below its
boiling point. |
|
Condensation
|
the change of state from a gas to a liquid.
|
|
Sublimation
|
the change of state from a solid directly to a gas.
|
|
States of matter
|
the physical forms in which a substance can exist.
(ex. Solid, liquid, gas, plasma) |
|
Solid
|
the state in which matter has a definite shape and volume
|
|
Liquid
|
the state in which matter takes the shape of its container and has a
definite volume. |
|
Gas
|
the state in which matter changes in both shape and volume.
|
|
Pressure
|
the amount of force exerted on a given area.
|
|
Plasma
|
the state of matter that does not have a definite shape or volume
and whose particles have broken apart. (ex. Lightening, stars, auroras) |
|
Viscosity
|
a liquid’s resistance to flow.
|
|
Boyle’s Law
|
states that for a fixed amount of gas at a constant
temperature, the volume of a gas increases as its pressure decreases. |
|
Charles’s Law
|
states that for a fixed amount of gas at a constant
