Particles of Matter
What is matter?
Matter is made of particles on a scale that is too small to be seen.
Anything that takes up space and has mass
True and False and why
We can not see all properties with our eyes
True
answers may vary for example magnetism we would need to test with a magnet before we would know for sure.
When mixing Vinegar and baking soda how do you know it is a chemical change?
a gas is produced. It creates a whole new substance.
When water and sugar are combined
is physical or chemical and how do you know?
Physical Change. I can evaporate the water out and be left with sugar. There was no new substance.
_________Particles very loosely packed together. They take up the shape of their container but do not hold the shape.
Gas
What are the three types of matter?
How can we tell the difference between powder sugar, baking soda, and flour?
By testing their properties. One will have a chemical reaction with vinegar. One becomes pasty with water while one becomes more sticky.
_________ Change is done only to the physical properties of a substance and are often reversible.
Physical Change
Melting and ice cube
is physical or chemical and how do you know?
Physical.
There was not a new substance made. It can also be reversed. It just changed states.
_________________________Particles are packed together however allow flow. They also take up the shape of their container but do not hold the shape.
Liquid
True or False and why... I can always see solids, liquids, and gas
answers may vary
False, we can't always see gas. I see the air but I feel it with the wind.
Name 5 different properties
color, taste, magnetism, boiling point, density, solubility, hardness, conductivity.
_________ Change is when a new substance is made
Chemical Change
Rotting Bananas
is physical or chemical and how do you know?
Chemical
react with the oxygen in the air. When exposed to the air, these chemicals react in a process known as oxidation, turning the fruit brown.
______________________Particles are packed tightly together however they are still moving very slowly. They hold the shape of their container.
Solid
All Matter is made up of
Particles / atoms
Metabolism
is physical or chemical and how do you know?
is the chemical reactions in the body's cells that change food into energy.
True or False and why
Each type of matter has its own unique set of properties.
Metals have different properties (for example: conduct heat/electricity, some are magnetic) than plastics (for example: some plastics are bouncy/elastic). because the particles are arranged differently, they react differently when tested for certain properties.
Matter is never ____________ or ______________
Created or destroyed
Regardless of the type of change that occurs, Chemical or physical, when heating, cooling, or combining substances, the total weight of matter is____________.
Conserved
When matter is combined, whether or not a new substance is made or not, the _____________always stays the same.
weight
