Convection, Conduction, Or Radiation?
The sun is transferring heat to the Earth.
What is Radiation?
The source of most radiation
What is the sun?
This is how convection energy travels.
What is circular movements?
Which one is an example of conduction? 1. Rubbing hands together 2. A microwave heating up something 3. The sun shining down
What is rubbing hands together?
The microwave transfers heat to the thing inside it.
What is Convection?
For radiation, would you warm your hands ABOVE a fire, NEAR a fire, or IN the fire?
What is near a fire?
This is how convection transfers energy.
What is Gasses/Liquids Rise And Sink?
This is how conduction is transferred.
What is Contact?
A lamp that produced heat was turned on.
What is Radiation?
Radiation uses these types of waves to heat things.
What are Transverse Waves?
Which of the following uses convection? 1. Normal Microwave 2. A fire 3. Toasters
What is a fire?
For conduction, would you warm your hands ABOVE a fire, NEAR a fire, or IN/TOUCHING the fire?
What is in/touching the fire?
Somebody touched a frozen pond and felt cold. What type of heat transfer is this?
What is Conduction?
This is ABOUT the percentage of radiation energy absorbed by the EARTH.
What is 50%?
In convection, this is what the warm air does and what the cold air does.
What is cold air sinking and warm air rising?
If you blow on a fire, it causes conduction. TRUE or FALSE?
What is false?
The heater was running and blowing warm air out of it.
What is Convection?
The approximate percentage of radiation energy absorbed by the clouds.
What is 20%?
There is convection in an oven. TRUE or FALSE?
What is true?
If there is a forest fire spreading, it is an example of conduction. TRUE or FALSE?
What is true?
