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, 355 m. L, 3 cm³

More Qualitative Properties of Matter 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 Temperature Melting 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=lxwxh h = height w = width l = length
What are some of the units of measurement we use to measure volume?
How do we measure the volume of uniquely shaped object? Eureka!
