Temperature and HeatHeat is a flow of energy dueto temperature differences Temperature Depends onParticle Movement . All matter is made up of atomsthat are moving even solidobjects have atoms that arevibrating The motion from the atoms gives.the object energy The Kinetic Theory of Matter All of the particles that make up matter are constantly in motion Solid vibrating atoms Liquid flowing atoms. Gas move freely Plasma move incrediblyfast and freelywww nasa gov. Temperature The Measure ofthe average kineticenergy of all theparticles in the. The atoms massdetermine thetemperature of thecse ssl berkeley edu Temperature. Temperature ismeasured in units calleddegrees oC F K Fahrenheit Waterfreezes 32oF and boils at. Celsius Water freezes at0oC and boils at 100oCwww germes online com How does a Thermometer The thermometer can measure.temperature because thesubstance of the liquid insidealways expands increases orcontracts decreases by a certainamount due to a change in.temperature All gases liquids andmost solids expandwhen theirJoints such as.temperaturethis one areincreases used in bridgesaccommodate This is why bridges are.built with short expansion segments with small Reproduced bybreaks to allow for permission ofexpansion JLM Visuals . Energy Flows from Warmer toCooler Objects Heat the flow of energy from anobject at a higher temperature toan object at a lower temperature . Thermal Energy total randomkinetic energy of particles in an Measuring Heat Heat is measured by the units ofcalorie and joule J . calorie The amount of energyneeded to raise the temperature of1 gram of water by 1oC 1 calorie 4 18 J Some substances change.temperature more easilythan others Specific Heat theamount of energyrequired to raise.the temperatureof 1 gram of asubstance by 1oCchesapeake towson edu The Transfer of Energy as. Energy moves heat in three ways Conduction Convection Radiation Conduction. The process that moves energy from oneobject to another when they are touchingphysically Conductors materials that transfer energy Insulators materials that do not transfer.energy easily Examples hot cup of cocoa transfers heatenergy to cold hands Convection The process that.transfers energyby the movementof large numbersof particles in thesame direction.within a liquid or Cycle in Nature Boiling water andheating a roomwww physics arizona edu.
