Why is it important to know these properties of matter?
States of Matter and TemperatureMelting Point – The characteristic temperature at which a materials melts (goes from ____ to ____)The melting point for water is ___ °C.
Freezing Point – The characteristic temperature at which a material freezes (goes from ____ to ____) The freezing point for water is ___ °C.

Mass:
Mass describes the amount of matter that makes up an object.
Volume:
Volume describes the amount of space that an object takes up.
V = l x w x h
l = length w = width
h = height
