Classifying Matter
What are the two categories that matter can be categorized as?
Pure Substance and Mixture
What does magnetism mean?
using a magnet to separate materials that are magnetic from a pile.
Tony and Andy are have a debate on the particles inside a solid. Andy states that particles inside solids are tightly packed therefore there will not be spaces between them. Tony disagrees with Andy, Tony states that no matter how tightly packed the particles are, there will still be spaces between them.
Who is correct in this situation?
Tony.
What are the 3 states of matter? Provide an example for each.
Answers will vary for examples
This planet is known as the “Red Planet.”
What is mars
What is a pure substance? Provide an example.
Pure Substance - one type of particle throughout the substance, can not be separated into different parts.
Examples will vary.
Cindy is trying to remove the pebbles she accidentally dropped from the flour used to make cake. What methods of separation can she use?
- Tongs
- Sifting
True or False:
Particles inside an ice cube are moving
True
Which state will have the slowest moving particles?
Solid
The process by which plants make their own food using sunlight.
What is photosynthesis
What is Sea water classified as?
-Pure substance or Mixture?
-Homogenous or Heterogenous?
- Homogenous
Describe the difference between floatation and sedimentation. How will the two help with the separation of substances? Would the process be considered as heterogenous or homogenous?
Floatation - Float on the top ( less dense), scoop the top layer to separate
Sedimentation - sink to the bottom (more dense), remove the top layer and keep the bottom layer
Heterogenous
What are the four points to the particle model of matter?
- Particles are always moving
- Particles have spaces between them
- Particles are attracted to each other
- Everything is made up of particles
Which state will have no definite shape but definite volume?
Liquid
This is the largest organ in the human body.
What is the skin
Is this mixture Homogenous (H) or Heterogenous (T)
- Apple Juice
What is homogenous (H)
Village A is experiencing a drought, Jackie spent days collecting water in a bucket, just when he was about to boil the water to drink it, a huge gust of wind blew large amounts of sand into his water bucket.
What is the best method for Jackie to use to get clean water?
- Filtration or Sedimentation
Describe why stirring sugar inside water will help it dissolve faster using the particle model of matter.
Break down the bonds between sugar to help water bond to sugar more. (Attraction)
- Adding heat when stirring
What is required for state change? Think about : solid to liquid, liquid to gas
Why?
Heat
Heat breaks bonds, allows particles to move faster
The author of the play Romeo and Juliet.
Who is William Shakespeare
Give an example of a heterogeneous mixture
What is bowl of MnM's
Describe the difference between distillation and dehydration. Provide a situation for each of the methods ( when will you use the method?).
Answers may Vary
Dehydration - recover the solution, evaporating away the liquid portion.
Distillation - recovering the solvent. Separating two solutions at different boiling points. ( using evaporation and condensation)
Describe why sugar is able to dissolve in water while oil is not? USE the particle model of matter.
Water particles are more strongly attracted to sugar particles than to themselves. Water particles are more attracted to themselves than to oil particles.
What is deposition
This element has the chemical symbol “Fe.”
What is iron
