Liquid: D and E.
Gas: F.
2.
Into liquid on warm day (37 °C): D and C.

Explanation:
Hello!
In this case, since the melting point is the temperature at which a substance change from solid to liquid and the boiling point from liquid to gas, we understand that substance at a temperature below the melting point is solid, whereas above are liquid; moreover, below the boiling point they are liquid and above gaseous.
In such a way, we have:
1.
Solid: A, B, and C.
Liquid: D and E.
Gas: F.
2.
Into liquid on warm day (37 °C): D and C.
Into a liquid only when heated slightly: C and E.
From liquid to solid readily when placed into a freezer (0 °C): D.
