Clues

1. Just like solid → liquid → gas goes from coldest to hottest, the three digits in the code go from smallest to biggest, left to right.
2. The number 6 is in the code — like the 6 sides of an ice crystal, which is a solid, the coldest state of water.
3. The last digit is 9 — gases are the hottest state, and 9 is the biggest digit, so it goes last!
4. A liquid is warmer than a solid — so the middle digit is bigger than the first digit.
5. Add up all three digits in the code and you get 18 — the same number of degrees difference between the three states in our puzzle!
