Question

NAME A LIQUID WHO AFTER HOTNES BECOME H SOLID​

Answer 1

solution composed of α-cyclodextrine (αCD), water and 4-methylpyridine (4MP) shows this unique property. It becomes solid when

 heated between 45 and 75 degree Celsius, and becomes a liquid when cooled again. Hydrogen bonding is behind this phenomenon

Answer 2

I think it is milk because, when it is cool then it is liquid but, when we boil it then cream is formed over it which is solid and again sometimes when the milk gets soured and we boil it then posset is formed which is solid.
