4.1 Science (Studying matter)

• matter is anything that has mass and takes up space
• By studying matter, scientists can better understand the property of chemicals
• Matter is assigned to different types due to its composition
• Matter can be classified to pure substance or mixture
• The simplest form of matter are elements as they can not be broken down
• What is an example of the simplest form of matter?A

  All elements on the periodic table
• Two or more elements make a compounds
• Elements and compounds are both pure substances
• Two pure substances make a mixture
• The mixture is a combination of two or more substances that can be further seperated physically
• Mixture can be either Homogeneuous or Heterogeneuous
• What are the classifications of mixtures

  Homogeneous or Heterogeneuous
• Homogeneous looks the same
• Heterogeneous is when the substance isn't fully dissolved
• What is another name for homogeneous?

  Solutions
• What are the classifications for Heterogeneous?

  Colloid, Suspencions
• What are colloids

  Looks dissolved but isn't microscropel
• Colloids look disolved but isnt microscopely
• What are solutions?

  When the solute is 100% dissolved in the Solvent
• Solutions are when the solute is fully dissolved in the solvent
• Suspencions are when some parts of the substance is suspended to the botton but not fully discolved
• What are suspencions?

  When the solute isn't fully dissolved and parts of the substance is suspended to the bottom.
• What is the acronym for the particle theory of matter?

  toamt
• What does t mean?

  Tiny particles
• What does o mean?

  own kind of particle
• what does a mean?

  attract
• What does m mean?

  moving
• What does t mean?

  higher temperature
• All matter is made out of tiny particles
• Each pure substance has its own kind of particle
• Particles attract eachother
• Particles always moving
• Particles higher temperature move faster then average
• toamt meaning?

  tiny particles, own kind, attract, moving, higher temperature
• What is the first rule of the particle theory?

  All matter is made out of tiny particles
• What is the second rule of the particle theory?

  Each pure substances has its own kind of particle
• What is the third rule of the particle theory?

  particle attract eachother
• what is the fourth rule of the particle theory?

  Particles are always moving
• What is the fifth rule of the particle theory?

  Particles higher temperature move faster then average
• Mixtures are physically combined
