Wednesday, February 3 rd, 2016 Heat Engines!

Today’s Targets  I can identify the transfer of energy among the 6 “Forms” of energy (#3)  I can use the Conservation of Energy and the mathematical definition of PE and KE to solve calculations questions about falling objects. (#7)  I can explain how heat, temperature, and thermal energy are all related (#8)  I can describe how thermal energy is transferred through conduction, convection and radiation (#10)

Today’s Agenda  Warm-Up (distribute quiz #1)  Quiz #1 review and preparation for tomorrow’s requiz  Heat Engines….a simple energy transformation

Warm Up  Make an energy chain for the following:  A wind turbine charging a battery  A solar powered car  A battery operated flashlight  A battery operated radio  A person playing the piano

Quiz Review  Woah…. Let’s take a look at the most missed problems in preparation for tomorrow’s re-quiz

A Heat Engine

Warm-Up  A measure of the TOTAL kinetic energy of the particles that makeup an object is that object’s _______________. This is measured in __________.  A measure of the AVERAGE kinetic energy of the particles that makeup an object is that object’s _______________. This is measured in _________.  The flow of thermal energy is called ______________. This is measured in _________.  When materials are heated, the particles move ____________ and generally take-up more _______________. This is called _____________ ___________.  Materials generally increase more in _____________ than _____________. (cold vs hot ring)  Thermal Energy can be transferred in what three ways?  Draw an energy chain for the following PHET examples: space Joules Temperature Kelvin Heat Joules faster Thermal Energy Thermal Expansion length width Conduction, Convection, Radiation

Remediation Time!  Tomorrow, you will receive your quiz #1 back.  After completing the remediation sheets that you picked-up on your way into class today, you will have an opportunity on Thursday (during class) to redo quiz #1.  Let’s spend the time now breaking-down the steps to solve PE and KE problems.

Scenario….  I just brought 1kg of hot tea into the room.  Mass of tea is 1kg
