Yes. The chemical with the composition H2O is named as ‘water vapour’ when it is a gas, ‘liquid water’ or just ‘water’ when it is a liquid and ‘ice’ when it is a solid. However, the chemical itself is named ‘water’ (NOT “dihydrogen monoxide") regardless of its state.

If temperature of water falls below or at freezing point then liquid state of water gets transformed to solid water which is termed as ice. The density of ice is less than water,hence ice floats on water. Which is very rare, because usually solid state of substance has more density than its equivalent liquid state.

Sure yellow is yellow. However humans does not have cones to register yellow as a single wavelenght and therefore, everytime you see something yellow, your L and M cones fire at the same time (L being red and M being green) which means yellow can be composed of red and green. So you wouldn't know if its a mix or a clean yellow, since your eyes tells your brain to fire the red and green cones, when yellow appears to you. (Orange is also a mix of red and green btw) :)

Hot ice is a common name for sodium acetate trihydrate.
Solid at room temperature, it melts into a liquid at 58 degrees Celsius.
It can also be melted into a liquid and then supercooled, getting it down below its freezing point without having it crystallize. Then, when some disturbance point -- or a nucleus for crystals to form around -- is introduced, the rest of the liquid rushes to solidify as well.

Simple but hard. If you believe that water is wet then ice is not wet because it’s ice. If you don’t believe that water is wet then ice is still not wet.

Water cannot be taken below the freezing point. Ice water has a temperature of 0°C.
But once frozen, the temperature of ice can be reduced to well below freezing. Ice from my freezer icemaker is -20°C. Ice in the Arctic can be -40° or even colder.

Technically, no. It is a mixture of ice and air.
There are other nuances and technical considerations.

What is more cold, ice or ice-cold water? Why?
Ice can be made much colder than ice water.
Water cannot be taken below the freezing point. Ice water has a temperature of 0°C.
But once frozen, the temperature of ice can be reduced to well below freezing. Ice from my freezer icemaker is -20°C. Ice in the Arctic can be -40° or even colder.

Obviously, it’s ice that’s colored yellow! The what that is coloring it yellow would determine “what” it is.
