water is made of H2O molecule. 2 hydogens and one oxygen.
Hot water freeze faster than cool water. It cool faster because when a substant is warm the molecules are spead out that way it
would easyly freeze. coolin system would attack one. Just think of it this way. when the molecules are spread out the are are smaller than when they are together

It depends of what you mean by quicker. Hot water will have less dissolved gas and that could affect the freezing point of the water. In that sense it might freeze more quickly in the sense that the temperature is higher when it freezes. But, there are still more calories to remove from the hot water and in that sense it takes much longer.

Water chemical formula is H2Owhich means 2 molecules of hydrogen and 1 molecule of oxygen.
Cold water freeze faster. The temperature is about 12 to 18 °C. The time of temperature depression is shorter.
Hot water takes longer to freeze coz the boiling point of water is 100°C, so it needs more time to
decrease at O°C which is the freezing point of water.

Water is made of the same stuff everything else is made of, protons, neutrons, and electrons. Of course you know the chemical formula of water is H2O, and as for your second question... it depends vehmently on the conditions. It is 'possible' for hot water to freeze before cold water but it only happens under specific conditions. This is known as the mpbema effect. Try to google 'mpbema' and you'll find a whole slew of info on the topic
cheers,

Water is composed of Hydrogen and Oxygen chemically joined. Hot water looses heat faster than cold but it depends on the temperature and how much heat must be removed.

water is a compound made of covalently bonded two oxygen atoms to one hydrogen atom. Water molecule has bent shape.
cold water freezes quicker.

water's a compound of two hydrogen molecules and one oxygen molecule
and duh, cold water freezes quicker!
