H2O @ 1degree
Hint : What is water not at 1 degree? what isn't the state of water at 1 degree celcius
Please guys help me its a riddle and i'm stuck...No answer i thought fits in blank
UPDATE : solid,liquid or gas,ice,steam,snow,.... not fitting in blank
your question doesn't make sense - perhaps you should read it more carefully.
If you're asking what state water is in at 1ºC then a quick google of freezing point water will give you 90% of what you need
hint what temperature does water freeze at? Is 1ºC above or below that?
