Heat Transfer
Radiation is...
the transfer of energy by electromagnetic waves; infrared heat waves like in the Electromagnetic spectrum
Convection is...
the transfer of heat by the actual movement of the warmed matter; heated gas or liquid particles rise
Conduction is...
the transfer of thermal energy between matter that is indirect contact; heat transfer from a heat source through a solid
Heat is...
thermal energy that is in transit movement
Energy transfers by...
transferring from matter to cooler matter until both reach the same temperature
Wind is...
air in motion
Heat moves...
from place to place
The heat you feel when you touch a hot stove is an example of?
Conduction b/c you made direct contact.
Why you use a pot holder when getting the cookie sheet out of the oven is an example of?
Conduction b/c the cookie sheet has been heated.
The heat you feel from your electric blanket is an example of?
Conduction b/c the electricity warms the blanket that is covering (touching) you.
Why the kettle on the stove gets hot is an example of?
Conduction b/c the kettle is being heated.
My spoon is hot after leaving it on the pot that was on the stove is an example of?
Conduction b/c the pot warmed the spoon.
The transfer of heat by the actual movement of the warmed matter (i.e. gas or liquid) is an example of?
Convection b/c it heats the gas or liquid.
Insulation is used to prevent this type of heat transfer...
Convection b/c it prevents the loss of hot air.
This is responsible for making macaroni rise and fall in a pot on the stove.
Convection b/c it warmed the liquid in the pot.
Why the dog lays down next to the wood stove is an example of?
Convection b/c the air around the dog is heated.
Why the cat sits on a stove above the stove is an example of?
Convection b/c the air below the cat is heated and rises.
The heat you feel when you sit next to a campfire is an example of?
Convection b/c the campfire warms the air around you.
The reason heating vents are usually placed on the floor of a home is an example of?
Convection b/c the hot air rises.
The heat you feel when you put your hands above a fire is an example of?
Convection b/c you are heating the air around your hands.
Heating and cooling is...
a result of energy transfer
This type of heat transfer is trapped by green houses...
Radiation b/c the heat is created by the suns heat waves.
The heat my snake feels from the heat lamp above him is an example of?
Radiation b/c the lamp transmitted infrared heat waves.
Heat we feel from the sun is an example of?
Radiation b/c the sun warms us by the rays.
In what three ways does heat transfer?
Radiation, conduction, and convection
Wind develops as a result of...
area differences in atmospheric pressure, which occur b/c of uneven heating of solar radiation at the Earth's surface.
Wind is created by...
molecules wanting to go from higher pressure areas to lower pressure areas.
Wind speed tens to be at its greatest during...
the daytime when the greatest area extremes in atmospheric temperature and pressure exist.
The larger the pressure differences...
the greater the wind.
