Properties of Matter
A property of matter is defined as...
A characteristic that helps you identify a substance.
Properties you can measure include...
melting point, boiling point (freezing point is the same as melting point)
Mass is...
the measure of the amount of matter in a substance.
To measure mass directly we use...
A scale or balance.
Meniscus is...
When you have liquid in a graduated cylinder and it curves down in the middle, you take the bottom reading.
You use your senses to find these.
Colour, taste, odour, texture, clarity and lustre.
The melting point of ice would be...
0 degrees Celcius
A bag of potato chips would use this unit for mass.
grams (g)
To measure volume directly we use...
A ruler or measuring tape with the formula
Volume = length x width x height
Something less dense than water would be...
Many choices!
Wood, lily pads, ice, oil, boats, cork, styrofoam, etc.
If it floats, it is less dense than 1.0 g/mL and it will float.
The states of matter are...
solid, liquid and gas.
The boiling point of water would be...
100 degrees Celcius.
A human would use this unit of mass.
kilograms (kg)
To measure mass of a liquid indirectly we use...
A scale with and without a container.
Something more dense than water is...
Many choices!
Metal, rocks, glass, sand, syrup, glycerine.
If it sinks, it has a density of more than 1.0 g/mL.
What is matter?
It is anything that has mass and takes up space.
You can measure mass and volume. Are they properties of matter?
No they are not properties because knowing the mass or the volume is not unique to a material.
Volume is... and the units are...
The amount of space that something takes up in the world.
The units are mL or cm cubed.
To measure volume indirectly we use...
Displacement with a graduated cylinder and water.
Why is measuring volume by displacement an indirect measurement?
Because you are not measuring the volume of the object, you are measuring the volume of water and calculating the volume of the object.
Indigenous peoples have known the properties of this substance for thousands of years, and have used its properties to be able to extract it from nature.

You can calculate density. Is it a property of matter?
Yes. Density is a property of matter because the density of a specific substance should be constant.
For example, all copper has a density of 8.96g/mL, no matter how much you have or where it is from.
Density is... and the units are...
How much matter is in a certain space.
The units are g/mL or g/cm cubed.
What is a substance you can not use the displacement of water to measure the volume of?
Anything that will dissolve like sugar, salt.
Anything that will float will be harder to measure as well.
Your friend picked up a piece of coal from a firepit and said it was very light, so he said it would float in water. You disagreed, so you measured the mass to be 3 g, and the volume to be 2 mL. Find the density to determine if the coal would sink or float.
Density is mass/volume.
3g / 2mL = 3/2 g/mL = 1.5 g/mL
The coal is more dense than water, so it would sink.
