Heat Transfer
Which type of heat transfer happens when you burn your hand on the stove?
What is conduction?
Material through which thermal energy flows easily.
What are conductors
For which State of Matter are the particles most closely arranged with the least amount of motion.
An example of radiation is
the sun
microwave....etc
A friend tells you that insulation keeps out the cold. Explain why this statement is incorrect.
Heat is transferred from hot to cold. So insulation actually keeps the warm in, not the cold out.
materials that reduce heat transfer
Your chair, desk/table, and the metal legs are all ________ temperature
Room
Which type of heat transfer happens when you get a sunburn during a baseball game?
Radiation
What material is a good example of a conductor?
metals, ceramics, stone
In the Thermal Lab -Pre Lab simulation, which materials displayed a change of state?

What are the 3 types of heat transfer?
Conduction, Convection, Radiation
A good handle for a pot or pan, is usually made out of:
ruber, glass, silicone, plastice, rubber, wood
(or rarely a heat resistant alloy)
(INSULATORS)
When you touch your desk, why does the metal feel colder than the top of the desk even when they are the same temperature?
The metal absorbs heat from your hand faster then the desktop/tabletop
The ocean currents that circulate through the water, and the Thermal air currents in the air are an example of this type of heat transfer
convection
