Chapter 6: Section 2 Temperature
What is temperature? • Any ideas? • Think, pair, share(1min)
2 things you need to know: • All things are made of atoms or particles that are too small to see
Particle Movement in a Solid, Liquid, Gas • Students as particles demo
Back to Temperature The measure of kinetic energy of the particles in an object Kinetic energy of particles Temperature =
Measuring Temperature • 2 ways: • Fahrenheit Scale: At what temp does H2O freeze?________ At what temp does H2O boil?____
Measuring Temperature 2. Celcius Scale: At what temp does water freeze?_____ At what temp does water boil?_____
What is heat? • Think about this: • What happens to your hand when you grab a cold drink out of the fridge?
Heat • The transfer of energy from one object to another • Flows from warmer to cooler objects
Let’s go back to this situation Knowing what you know about heat…think about this: • What happens to your hand when you grab a cold drink out of the fridge?
Midpoint Review • How are temperature and kinetic energy related? • Heat is transferred how?
Heat Transfer • There are 3 types: • Conduction • Convection • Radiation
Conduction Transfer of energy by collisions of molecules in a material (2 things touching) Usually happens in solids
Which spoon would you rather cook with? metal wooden Metal is a good conductor
Insulators • Some things are bad conductors • They can be used as insulators • Sweaters • Blankets • Plastics • Wood • rubber
Convection • Heat is transferred between objects of different temperatures • Most common in gases and liquids
Examples of Convection Birds can float with out flapping wings Heating your home
Radiation • Transfer of heat energy by waves
Examples of Radiation • Heat from fire • Microwave heating food
Heat • BrainPop
Quick Review • Heat is transferred from ______ things to _______things. • What are the 3 types of heat transfer? • This is more common in solids____ • This is more common in liquid/gas_
