Sizzling — Convection Convection Chimneys
Hi!
I'm Sizzling.
Welcome to Convection Chimneys!
Will you help me investigate convection?
The Grumblies have mixed up our clues.
Let's check the evidence!
Convection transfers energy through motion in liquids or gases.
Warmer fluid often becomes less dense and rises
while cooler fluid moves into its place.
Which materials can show convection?
- A. Only empty space
- B. Liquids and gases
- C. Only rigid solids
The answer is B: Liquids and gases
Convection transfers energy through motion in liquids or gases.
Warmer fluid often becomes less dense and rises
while cooler fluid moves into its place.
That clue helps us make sense of this place.
Circulation can carry energy around a system.
The phrase warm air rises describes moving air;
heat itself is not a material that only travels upward.
What rises in the supplied model?
- A. Warmer air
- B. Only an empty label called heat
- C. The whole solid chimney
The answer is A: Warmer air
Convection transfers energy through motion in liquids or gases.
Warmer fluid often becomes less dense and rises
while cooler fluid moves into its place.
Hmm...
how does that connect to our first clue?
Our chimney model shows warmer air rising and cooler air returning below.
Trace both parts of the loop
rather than drawing only a one-way disappearing stream.
What completes the circulation loop?
- A. All air leaving existence
- B. All air becoming solid
- C. Cooler air returning
The answer is C: Cooler air returning
Our chimney model shows warmer air rising and cooler air returning below.
Trace both parts of the loop
rather than drawing only a one-way disappearing stream.
Nice investigating!
