Science Q3

• Matter - anything that occupies space and mass either be living or non-living
• Matter - made of tiny particles called atoms or molecules  
• Solid - particles that are ightly packed and move around very little
• Liquid - has weaker attractive forces that allow particles to flow around each other
• Gas - particles with the highest amount of energy
• Gas -this energy allow the particles to move fast and have a great space between them
• Plasma -fourth state of matters
• Plasma - it is often seen in ionized gases in which many of the electrons wandering around freely among the nucle of the atoms
• Base-Einstein Consensate - fifth state of matter
• Base - Einstein Consensate - created when particles called bosons are cooled to near absolute zero
• Chemical - can be observed by changing the identity of a substance
• Properties - distinguished characteristics that you use to identify matter
• Physical - properties are the characteristics that can be observed without changing the substance into another substance.

  Color, taste, odor, state of matter, density, melting point, and boiling point
• Chemical - when the substance reacts with another substance and undergo change in its composition.
• Physical changes - changes in the physical properties of matter.
• Melting - is the physical change of a solid to a liquid by the addition of heat
• Freezing - is the change of state in which a liquid becomes solid as heat is removed
• Evaporation - is the change of substance from liquid to gas by adding heat
• Condensation - is the change of state from gas to liquid by removing heat
• Sublimation - is the process in which a solid change directly into a gas
• Deposition - is the process in which a gas changes directly to a solid
• chemical change -, occur when the composition of a substance is changed into a substance completely different from the original.
• Pure substances - made of identical particles. All the particles of a pure substances are the same throughout.
• Elements - substances that are made up only one type of atom and they cannot be broken down into simpler substances.
• Compounds - substances that are made up of more than one type of atom. These can be separated into two or more simpler substance.
• Mixtures - made up of non-identical particles.
• Mixture - two or more kinds of matter are put together
• Decantation - The particles of mixtures are settling down and less dense particles are poured off.
• Distillation - As heat is applied, water evaporates, and white crystal residues remain.
• Filtration - Water passes through a filter paper and the mud remains on the filter paper.
