True or false about water?

Hi! I have some questions about the unique attributes of water.

Is solid ice less dense than liquid water? (I know that the density of water decreases between 0 to 4) But what if the solid ice is below 0degree? Is it still less dense than liquid water?Also, does the water contract as it freezes at 0°C?Thank you in advance!

    The density of ice is 0.917 g/cm³ at 0°C and standard atmospheric pressure. Density of ice increases slightly with decreasing temperature and has a value of 0.9340 g/cm³ at −180 °C (93 K).

    Given that density of water varies between 0.9998 and 0.9997 (close to freezing), ice is always less dense that water and will always float.

    no, it expands as it freezes as the density goes down. If you take a full glass sealed bottle of water and freeze it, the glass will shatter as the volume tries to increase.

    "is solid ice less dense than liquid water?"

    yes, that's why icebergs float

    "does the water contract as it freezes at 0°C?"

    no, it has maximum density at +4 degrees celsius.

    advice: put a lot of ice cubes in one small spot and you got a black hole
