Radiation
Examples of radiation are
Laser pointer, microwave, sun/fire, reptiles in the sun or under a heat lamp, feeling heat standing by a stove or fire
(?) is heat transfer through a substance, requires CONTACT
Conduction
Examples of convection
Boiling water/tea, hot air balloon, wind, weather, hurricanes.
An item that slows down or stops energy or heat transfer
An insulator
A(?) is the movement of heat through matter where heated matter expands and rises and cooler matter condenses and sinks
what is a convection current?
Radiation is heat transfer by waves, travels at the speed of light, energy from the sun
What is radiation?
The collision of particles in matter will transfer heat by
Conduction
(?) is heat transfer through a gas or liquid that rises or falls.
Convection
Something that allows heat or energy to transfer through easily.
conductor
(?) will cause matter such as a gas or a liquid to expand and rise
heat
True or false Radiation can travel through the vacuum of space and matter
TRUE
Conduction happens mostly in what type of matter?
solids, requires contact
Convection occurs because there is a difference in ?
Convection occurs due to differences in temperature.
(?) allow heat and energy to travel easily while (?) slow down or stop heat and energy movement
Conductors allow heat and energy to travel easily while insulators slow down or stop heat and energy movement
What word that starts with e is what we call the energy from the sun, it is (?) radiation
Electromagnetic
Radiation does or does not require CONTACT
does not
Examples of conduction are:
feet on hot sand, food on a baking sheet cooking, pot on a hot stove
Weather, wind, tornadoes, and hurricanes are examples of
convection
Examples of conductors
METALS, silver, gold, copper, steel
What is the difference between convection, conduction and radiation?
-Convection = motion in which a gas or liquid rises or falls
-Conduction = transfer of heat using a substance
-Radiation = heat transfer coming from a source, moving at the speed of light.
True or False Radiation comes from the sun to Earth in many forms that we use everyday.
TRUE
What is the saying I told you to help you remember CONDUCTION?
Ouch, touch
In convection (?) rises and (?) sinks
In Convection, heat will rise, pushing cooler temperature matter out of the way, cool sinks
Examples of insulators
plastic, rubber or wood.
