CHEMISTRY

• Solids


  Particles are compacted, it has definite shape and definite volume
• Liquids


  Particles are slightly far apart, it has indefinite shape and definite volume
• Gases


  Particles are well separated, it has a high frequency
• Plasma


  Ionized gas, along with solids, liquid and gas
• Bose Einstein Condensate


  Matter that socializes
• Fermionic Condensate


  Atoms cannot stick together because it is anti-social
• Matter


  Anything made up of particles, it has a mass and volume, it is anything that occupies space and has mass
• Physical property


  A property of matter that can be observed or measured without changing the composition or identity of the substance
• Color


  A physical property of how the object absorbs and reflects light
• Temperature


  A measure of average kinetic energy of particles in a substance, melting point and boiling point
• Mass


  The amount of matter in an object
• Volume


  The amount of space an object occupies
• Density


  The amount of mass in a given volume/ratio of mass to volume, a substance is always the same of a given pressure and temperature regardless of the size of the sample of the substance
• Density equals to mass divided by volume
• Ductility


  The ability to be drawn or stretched or pulled into a wire
• Luster


  The way that a substance reflects light
• Solubility


  The ability to dissolve in another substance
• Thermal conductivity


  The ability to transfer thermal energy from one area to another
• Chemical property


  A property of matter that describes a substance based on its ability to change into a new substance with different properties
• Physical change


  A change that affects one or more physically properties of a substance. It does not form new substances. Can be often undone
• Chemical change


  A change that occurs when one or more substances are changed into entirely new substances with different properties. Cannot change back under normal conditions
• Endothermic


  Energy absorbed causing a decrease in temperature of the reactant material
• Formation of bubbles


  Can indicate the presence of a gas
• Formation of precipitate


  When two liquids are combined and a solid is produced
• Matter can be physically separated in homogenous mixture
• Matter cannot be physically separated in heterogenous mixture
• Elements


  Only one kind of atom, atoms are bonded in the element is diatomic and polyatomic
• Compounds


  Two or more kinds of atoms that are physically mixed
• Mixtures


  Two or more substances that are physically mixed
• Similarities of Element and Compounds (substance with definite make up and properties)
• Substance


  A matter that has definite or constant composition and distinct properties
• Element


  A substance that cannot be separated into simpler substances by chemical means
• Compound


  A substance composed of two or more elements chemically united in fixed proportions
• A given compound always contains the same, fixed ratio of elements ( LAW OF DEFINITE COMPOSITION)
• Elements can combine in different ratios to form different compounds ( LAW OF MULTIPLE PROPORTION)
• Mixture


  Variables combination of two or more pure substances
• Homogenous


  The composition is uniform
• Heterogeneous


  The composition is not uniform
• Colloid


  Any substance consisting of particles substantially larger than atoms or ordinary molecules but small to be visible
• Chromatography


  A separation technique used to separate the different components in a liquid mixture
