Qualitative and Quantitative Properties of Matter

Qualitative VS. Quantitative

Qualitative: A characteristic of a substance that can be observed and described in words that does not use numerical value.

Ex. Small, heavy, grey, smooth

Quantitative: A characteristic of matter that can be measured and described with numerical value.

Ex. 37°C, 25 lbs, 355mL, 3cm³

Qualitative Properties

Quickly scan p. 109 in your textbook.

Why is it important to know these properties of matter?

Quantitative Properties

Temperature: Temperature

measures how hot or cold matter is.

States of Matter and Temperature

What do we already know?

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.

Boiling Point – The characteristic temperature at which a material boils (goes from ____ to ____) The boiling point for water is ___ °C.

How else can we measure matter?

Remember, all matter has two things in common:

Mass and

Volume

Mass:

Mass describes the amount of matter that makes up an object.

What are some of the units of measurement we use to measure mass?

Volume:

Volume describes the amount of space that an object takes up.

V = l x w x h

l = length w = width

h = height

What are some of the units of measurement we use to measure volume?

How do we measure the volume of uniquely shaped object?

Eureka!
