Mixling — Planning a Separation Secret Recipe Vault
Hi!
I'm Mixling.
Welcome to Secret Recipe Vault!
Will you help me investigate planning a separation?
The Grumblies have mixed up our clues.
Let's check the evidence!
A separation plan can combine several property-based steps.
Track every component so recovered material is accounted for.
Which step removes iron?
- A. Evaporating every component
- B. A magnet
- C. Ordinary filtering of dissolved salt
The answer is B: A magnet
For iron, sand and salt water, a magnet can remove iron,
a filter can remove sand, and evaporation can leave salt behind.
Recovering the water too requires capturing
and condensing vapor in a suitable model.
That clue helps us make sense of this place.
For iron, sand and salt water, a magnet can remove iron,
a filter can remove sand, and evaporation can leave salt behind.
Recovering the water too requires capturing
and condensing vapor in a suitable model.
What removes undissolved sand?
- A. A filter
- B. Only waiting for a magnet to attract it
- C. Only cooling the magnet
The answer is A: A filter
For iron, sand and salt water, a magnet can remove iron,
a filter can remove sand, and evaporation can leave salt behind.
Recovering the water too requires capturing
and condensing vapor in a suitable model.
Hmm...
how does that connect to our first clue?
Our closed collection model keeps all components.
If water vapor escapes in an open model,
the remaining mass is smaller because material left, not
because matter was destroyed.
How can a model recover evaporated water?
- A. Pretend the vapor no longer exists
- B. Destroy the vapor
- C. Capture and condense the vapor
The answer is C: Capture and condense the vapor
For iron, sand and salt water, a magnet can remove iron,
a filter can remove sand, and evaporation can leave salt behind.
Recovering the water too requires capturing
and condensing vapor in a suitable model.
Nice investigating!
