1)Water takes this form above 100c (solid, liquid or gas)
olga55 [171]

Answer:

I say the 1st one I'm so terrible sorry if I'm wrong

Explanation:

Water can take many forms. At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas (steam).

The state the water is in depends upon the temperature.  Each state (solid, liquid, and gas) has its own unique set of physical properties.
