Heat on the Move
Heat always moves in this direction.
What is from warm to cool?
This type of heat transfer travels in "waves" like light from a lamp or the sun.
What is radiation?
This type of material, like aluminum, transfers heat energy much more easily than wood.
What is a conductor (or metal)?
This color of clothing will absorb the most radiant heat energy in the sun.
What is black?
When you put a hot boiled egg into a bowl of cold water, this is the direction the energy is transferred.
What is from the egg to the water?
When you put a hot egg in cold water, energy moves from the egg into this.
What is the water?
This type of transfer happens when vibrating atoms collide with their neighbors in a solid.
What is conduction?
We wear these in the winter to reduce heat loss from our bodies.
What are sweaters (or blankets)?
Light-colored clothes keep you cool because they do this to radiated heat energy.
What is reflect it?
This is the reason a metal spoon becomes too hot to touch in boiling water while a wooden spoon stays cooler.
What is because metals conduct heat better than wood?
If a cold soda makes a counter feel cold, it is because heat moved from the counter into this.
What is the soda can?
This type of transfer happens in fluids (air or liquid) when warm masses rise and cool masses sink.
What is convection?
This natural material is a great insulator for keeping a soda cold because it traps air.
What is wool?
This shiny material was used to reflect radiation in our "igloo" and house demonstrations.
What is Mylar (or a space blanket)?
When a cold can of soda makes the countertop underneath it feel cold, it is because heat has been transferred from the counter to this.
What is the soda?
As water turns into ice in a freezer, the air in the freezer does this to the heat from the water.
What is absorbs it?
This is why the upstairs rooms in a house are usually hotter than the downstairs rooms.
What is warm air rising (convection)?
This is the scientific term for a material that is a poor conductor of heat.
What is an insulator?
Using this kitchen appliance typically uses only about 6 gallons of water, compared to 20 gallons by hand.
What is a dishwasher?
After sitting in a freezer all night, this is how the temperature of a plastic plate compares to the temperature of an aluminum plate.
What is they are the same temperature?
Two plates left in a freezer all night will eventually reach this state where their temperatures are exactly the same.
What is thermal equilibrium?
This specific method is how a metal coat hanger becomes hot all the way to the handle when the tip is in a fire.
What is conduction?
This is the reason a blanket cannot warm up a plastic doll.
What is because the doll has no internal heat source to trap?
This inventor and draftsman helped Alexander Graham Bell protect the telephone by drawing its first blueprints.
Who is Lewis Latimer?
According to our water data, this specific method of cleaning dishes uses 20 gallons of water per sink full.
What is washing dishes by hand?
