The States of Matter Solids Liquids and gases

 By JX and MC Completed as a Requirement for mavericks physical science

 Liquid molecules can move and push through the other molecules, that is why they can take any take freely.  Air molecules have way more energy then the liquid molecules witch makes them able to break away from there neighboring molecules allowing for them to float freely. Atoms and molecules in Liquids and gases

 It is a distributed force per unit area that acts within a fluids is called pressure.  Pressure can go any direction excepted for the direction were the force was applied.  Pressure also can come from collisions between atoms. Pressure

 Intermolecular forces are forces between separate atoms and molecules that are attractive at a distant but repulsive at close rang.  When distance is greater then the size of the molecules they get pulled together by force. Intermolecular forces

 Melting point is when a solid is changed to a liquid by energy.  Boiling point is the temperature that changes liquid to a gas with high temperature. Melting and boiling points of objects

 Materials have a wide rang of temperatures were they can melt  Most objects have a lesser density when it is water then when it was a solid.  As liquids turn in to solids they will often be separated slightly. Melting and boiling points of common substances

 Evaporation occurs when molecules turn from liquid to gas below boiling point.  Evaporation takes a lot of energy from the liquid because when they have to much energy and the liquid will evaporate to gas.  Conduction occurs when gas turns into a liquid at temperatures below the boiling point. Evaporation and condensation

 Conviction is when transferring heat from motion of water and fluid and gasses  Convection occurs because liquids expand when they heat up by burning gasoline of using electricity. Convection

 Air is 1,000 times lighter then water that is why you cant feel air  Earths atmosphere contains oxygen, 78 percent is nitrogen, one percent is water vapor and the rest is other gases. The atmosphere of earth

 In solids, molecules are combined tightly and are unable to move around except for vibrating in place.  All solids are able to obtain a shape due to the tightness of the molecules.  Solids also have a different property that make them hard or soft. Solid matter

 The strength of the object is determined by how well the molecules stay in place.  Elasticity describes the way a solid can bend and still go back to its original shape.  Ductility is when you can bend the metal into any thing you need. Mechanical Properties

 If the atoms in a solid is an orderly repeating pattern the solid is called crystalline.  Most natural solids that are found on earth are crystalline.  Metals are also made from crystalline just that they have a lot of them squeezed together. Crystalline solids

 Almost 10 percent of the things that you can touch around you at least has just a hint of plastic  Most plastics are amorphous witch means that they do not have a shape  Polymers are materials in witch individual molecules are made of long chains of repeating units. Polymer
