Introduction to Matter
Transcript of Introduction to Matter
matter? After swimming on a hot day, Eli was having a refreshing glass of ice water. As he rested by the pool, the water on his arm evaporated and the ice cubes melted in his glass.
In how many different forms does water exist in this example?
Ice, liquid water, and water vapor are examples of the three most familiar states of matter- Solid, liquid, and gas. Solid liquid gas All matter takes up space and is made of atoms! This means that matter has volume and mass! But what doesn't
have volume or mass? No seriously! Think about it!
What does not have
volume or mass? Examples of what has
mass and volume Examples of what does not have mass and volume metal spoon milk
ice cream humans electricity heat
sound 1. Matter is defined as anything with mass and volume Important Ideas to remember! But why does matter
have mass and volume
while stuff that is not matter
does not? Matter is made
of tiny particles
called atoms! Atoms are made up of Protons (+) , Neutrons (o), and Electrons (-) And, although
they are very tiny,
protons, neutrons, and
mass and volume. Matter has mass and volume because it is made of atoms!
Stuff such as light, sound, and heat, are NOT made of atoms! Thus, they are not matter 2. Matter is made of atoms Read through this prezi!
Take notes in your notebook. You will need to know/understand this information for activities, assessments, and labs.
Continue by pressing the arrow key below. MATTER! Not Matter! Every wonder why there are different states of matter? To understand why there are different states of matter, you need to understand a little more about atoms. Atoms contain energy Because of this energy,
atoms are always in motion! This idea is called the
Kinetic Theory of Matter So......
How does this relate to why there are different states of matter? Different amounts of energy Cause atoms to move at different speeds Which causes the different states of matter! What are solids? 3. The kinetic Theory of Atoms states that atoms are in constant
motion because they contain energy 4. How fast the atoms are moving determines the state of matter In the activity in class, you observed the particles of a solid You probably observed that the particles vibrated, but don't really move. What are solids? Solids have a defined shape and defined volume This is because the particles in a solid have a low amount of energy Low energy means the particles can vibrate, but cannot flow over each other This is why it is a solid! Because of the behavior of the particles, the solid acts likes.....well... a solid! What is a liquid? In the activity from class, you should have observed that as you added heat (energy) the particles began to move faster Moving faster caused the particles to loose their square shape. This is a liquid! This is because the particles in a liquid have a medium amount of energy Medium energy means the particles can flow over each other This is why it is a liquid! What is a liquid? A liquid have an indefinite shape but a definite volume What is a Gas? In the activity from class, you should have observed that as you added even more heat (energy) the particles began to move even faster Moving even faster caused the particles spread out and fill the container This is a Gas! This is because the particles in a gas have a high amount of energy High energy means the particles act all crazy and fill the container This is why it is a Gas! What is a Gas? Gases have an indefinite shape and an definite volume Summary: Solids have a definite shape and definite volume Liquids have an indefinite shape and definite volume Gases have an indefinite shape and indefinite volume The particles of a solid have a low amount of energy
The particles of a liquid have a medium amount of energy
The particles of a Gas have a high amount of energy I know we covered a lot throughout this prezi. Don't worry! We will go over all this information over the next few activities!
