Clues

1. Just like solid → liquid → gas gets hotter and hotter, the three digits in the code go from smallest to biggest, left to right.
2. Gas is the hottest state of matter — and the last digit is 9, the hottest (biggest) single digit!
3. Solid is the coldest state of matter — and the first digit is 3, showing a cool, low temperature.
4. If you add up all three temperature digits together, you get 18 — just like the three states of matter all add up to make the full picture!
5. The number 5 does NOT appear anywhere in the code — none of the state-change temperatures hit this number.
