TOPIC: Heat AIM: How is heat transferred?
What is heat transfer? Movement of heat from warm cool object Example = hot pan Heat moves from pan handle
3 types of heat transfer
1. Conduction Heat transfer in SOLIDS
Heat transfer by the direct contact of molecules
Fast moving molecules (have more heat) Bump into slower ones Start to move faster collide with other slower molecules…
Why can the girl on the right toast marshmallows without getting burned?
Conductor Material that allows heat to move through it easily Metals (copper & silver are the best)
Example: copper pipes (Heat exchangers in hot water tanks, under floor heating systems, and car radiators)
TOPIC: Heat AIM: How is heat transferred? Cont’d…
Insulators Do not conduct heat easily Wood, paper, wax, air, house insulation, plastic
2. Convection Transfer of heat in liquids & gases Liquid heated molecules move faster & farther apart less dense rise carrying heat with it
Example: warm air rises, cool air sinks
Convection currents Up & down movement of molecules due to changes in density
Convection Currents Inside the Earth
3. Radiation Heat transfer through space Can travel when no matter is present (vacuum) Heat energy from sun, stars, fire
Radiation from the Sun travels through empty space.
Radiation from the fire heats the marshmallow.

Types of HEAT Energy Transfers CONDUCTION Objects are in direct contact. Heat energy transfers when particles collide or objects in contact are TOUCHING.
Conduction, Convection, Radiation, oh my!!. Conduction –Involves objects in direct contact –2 objects in contact are at unequal temperature –Example:
Energy Transfer Chapter Methods of Energy Transfer Conduction Convection Radiation.
Conduction, Convection, Radiation. Conduction Transfer of heat by direct contact. Heat flows from the warmer object to the colder object. Solids are better.
The Heat is On!!! Fill in Notes on Heat and Heat Transfer “taking the heat and moving along”
Heat Energy. Heat is energy caused by the internal motion of molecules of matter Heat is energy caused by the internal motion of molecules of matter Heat.
The Transfer of Heat Energy. What is ENERGY? Energy is the ability to make things move or change. Matter is made up of particles that are always moving.

Methods of Energy Transfer The transfer of heat energy from a hot object can occur in three ways: Conduction is the transfer of energy as heat through.
Conduction Conduction is the transfer of thermal energy through matter by the direct contact of particles. Conduction occurs because all matter is made.

Heat (PS 1-2) 1. I can define temperature as the measurement of thermal energy and describe the way it is measured. 2. I can trace how thermal energy.
Question of the Day Label the heat movement as conduction, convection or radiation. 1.Lava Lamp2.Fire3.Spoon in soup.
Energy the ability to do work or to change something used whenever the location, makeup or look of something changes.
A Form of energy that is related to the K.E. of molecules. The motion of molecules produces heat. The more motion, the more heat is generated.
