matter

• is anything that occupies space and has mass.

  matter
• Matter may either be __ or ___.

  living or non-living
• STATES OF MATTER


  solid, liquid, gas
• Matter is made of tiny particles called ___ or molecules that are in constant motion and are held together by attractive forces

  atom
• These particles are arranged depending on their ____

  states/phase.
• The speed of these particles is dependent on the _____ they contain.

  amount of energy or heat
• Particles of ___ are tightly packed and move around very little.

  solid
• ___ has weaker attractive forces that allow particles to flow around each other.

  liquid
• ___ have particles with the highest amount of energy. This energy allows the particles to move fast and have great spaces between them.

  gases
• ___ is the fourth state of matter. It is often seen in ionized gases in which many of the electrons wander around freely among the nuclei of the atoms.

  plasma
• ___ is the fifth state of matter, created when particles, called bosons, are cooled to near absolute zero.

  Bose-Einstein condensate
• Bose-Einstein condensate is the fifth state of matter, created when particles, called ____, are cooled to near absolute zero.


  bosons
• Properties are the distinguished ___ that you use to identify different samples of matter.

  characteristics
• • Matter has two main kinds of properties:

  physical and chemical
• ___ ___ are the characteristics that can be observed without changing the substance into another substance.

  Physical properties
• ___ ___ can be observed by changing the identity of a substance or when the substance reacts with another substance and undergo change in its composition.

  Chemical property
• There are two types of changes that matter may undergo through

  physical and chemical
• ___ __are changes in the physical properties of matter.

  Physical changes
• Physical Changes Matter Undergo:

  melting, freezing, evaporation, condensation, sublimation, deposition
• is the physical change of a solid to a liquid by the addition of heat

  melting
• is the change of state in which a liquid becomes solid as heat is removed

  freezing
• is the change of substance from liquid to gas by adding heat

  evaporation
• is the change of state from gas to liquid by removing heat

  condensation
• is the process in which a solid change directly into a gas

  sublimation
• is the process in which a gas changes directly to a solid

  deposition
• A ___ ___ or chemical reaction, occur when the composition of a substance is changed into a substance completely different from the original.

  chemical change
• ___ are made of identical particles. All the particles of a pure substances are the same throughout.

  Pure substances
• Two types of pure substances:

  elements and compounds
• are substances that are made up only one type of atom and they cannot be broken down into simpler substances.

  Elements
• ___ are substances that are made up of more than one type of atom. These can be separated into two or more simpler substance.

  Compounds
• mixture are made up of ______

  non-identical particles
• When two or more kinds of matter are put together it is called ___.

  mixture
• Mixtures can be separated ___

  physically
• Methods to separate mixtures

  manual picking, decantation, distillation, filtration
• __ ___ is a mixture of two or more substances (elements or compounds), wherein different components cannot be visually distinguished and hard to separate.

  Homogeneous mixture
• They are evenly and uniformly distributed

  Homogeneous mixture
• A solution is a __ ___ of two or more substances in variable composition. This means that every portion of the solution is the same as any other portion but the amount of its components may vary.

  The parts of a solution are physically combined.
• Solutions are made up of two parts:

  solute and solvent
• is a mixture of two or more substances (elements or compounds), wherein different components can be visually distinguishedand easily separated by physical means.

  • Can easily be identified and separate.

  The particles are not evenly and uniformly distributed, and because of this we can easily see it and separate itfrom one another, since particle size of the substances that were mixed are different from each other.

  • Heterogeneous mixture
• gets dissolved


  solute
