Intro to Matter

Matter is anything that has mass and takes up space. Matter is made up of atoms.  Atoms take up space, have mass and are in constant motion. This course is worth 4 credit hours.

Matter Vocabulary

Matter Vocabulary

Take time to study these words:

matter:     Anything that has mass and takes up space.

physical properties: Characteristics of a substance that can be observed and measured without changing it into something else.

states of matter: solid, liquid, and gas

weight: The measure of the pull of gravity on an object.

volume: The amount of space an object takes up.

mass:  The amount of matter in something

density: The concentration of matter in an object   d = m/v

mixture: Two or more kinds of matter mixed together where they each get to keep their own physical properties 

solution: A combination of substances where one dissolves into another .

physical changes: Changes in matter where no new substances are formed.

chemical changes: Changes in matter where a new substance is formed.

solubility: Has the ability to be dissolved.

reactivity: The ability to react chemically with other substances.

Now that you have studied the vocabulary, see if you can match up the correct answers.

What Have You Learned?

What does it mean that matter is made up of particles? Give plenty of detail. Remember, you answer will be marked incorrect until I grade it.

Which of the following is evidence for the claim: "Particles are tiny and cannot be seen"?

  • Particles are everywhere.
  • You cannot see particles but you can smell them in the air.
  • Particle are very small, and you cannot see them.
  • Gas particles are spread out.

Why can liquids not be compressed easily?

  • The particles are in a random arrangement.
  • The particles are closely packed.
  • The particles are free to move over each other.

What is the name of the change when a liquid becomes a solid?

  • Melting
  • Boiling
  • Freezing

Why can't you put your hand through a solid table?

  • Because the particles are close together and in a fixed position.
  • Because the particles vibrate.
  • Because the particles are solid.
  • Because it does not move.

In which state of matter do the particles have the most energy?

  • solid
  • liquid
  • gas

What eventually happens if energy is continually removed from a liquid?

  • It boils
  • It evaporates
  • It freezes

Which state of matter has no definite shape and no definite volume?

  • Liquid or gas
  • Gas
  • Solid
  • Liquid

What is sublimation?

  • When a solid turns into a gas.
  • When a gas turns into a solid.
  • When a gas turns into a liquid.

In which state of matter are the particles mostly touching but arranged in a random way?

  • Solid
  • Liquid
  • Gas
