From Particles to Solutions
Chemistry 01
Learning Goals!!
• I will be able to explain the particle theory of matter.
• I will be able to classify matter using the terms: pure substance, element, compound, mechanical mixture and solution
What is CHEMISTRY!?
• The study of matter and the changes it undergoes
Matter …
• Anything that has mass and takes up space.
The Particle Theory of Matter
• All matter is made up of different kinds of particles
• Different substances are made up of different types of particles
• Particles are in constant random motion
• Particles move faster when heated, and slower when cooled
• Particles attract each other
Lists
• Create a list of 15-20 items you’ve used, eaten, seen, etc. in the last day or two.
• Save this list for later.
Pure Substances
• Made up of only one type of particles
• Any element from the Periodic Table
• Any compound (like distilled water, carbon dioxide)
Mixtures
• Made up 2 or more types of particles
• Mechanical mixture – you are able to see the different particles • pizza, oil and vinegar, cereal
• Solution – a mixture where you can’t see the different particles and you can see through it • apple juice, air in this room
• Alloy – a solid solution of two or more metals. • i.e. Bronze -> Copper + Tin
Classification of Matter
MATTER
PURE SUBSTANC
ESMIXTURES
ELEMENTS
i.e: H, O, C
COMPOUNDS
i.e: H2O, NaCl
SOLUTIONS
i.e: H2O + salt
MECHNICAL
MIXTURESi.e: H2O +
raisins
Can combine to form
Learning Goals Revisited
• I will be able to explain the particle theory of matter.
• I will be able to classify matter using the terms: pure substance, element, compound, mechanical mixture and solution
Task
• Go back to your list. Try to determine what type of matter each item is. i.e. if you had pizza it would be a mechanical mixture.
• Share list with your partner
• Complete poem Qs
• Textbook p178 #2-6, 8.
