Well i Have actually done the test for myself hot water freezes in my freezer quicker than the cold water ....I did this about 5 years ago and I was shocked ...I used to could tell you why it would but I have lived too much life and I forgot more than I will ever know!! LOL
Room temperature water freezes faster. In order to make water freeze, it has to be cooled to below 0 degrees C. Assuming that you are trying to cool this water by placing it in a subzero area (like a freezer or outside if you live in a cold place), it will take longer for the environment to absorb 100 degrees of heat than 25, since the rate of cooling will be the same for both.
Boiling water may boil off impurities which would lower the freezing point of water. For example, if your water contains 25% alcohol, if you boil half of it and then restore it to room temperature, the half that you boiled will freeze faster than the half you did not, since the boiling removes the alcohol which has a lower freezing point than water. (That's why you can safely store booze in the freezer)
No. The heat from boiling a seed would actually kill it. Soaking a seed in water before planting may help it grow faster, but the water should be room temperature.
The answer depends on the temperature of both water. But salt would dissolve faster in boiling water than it could in carbonated water at room temperature.
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.

room temperature water. the hotter water get the more quickly it moves

The water will slowly evaporate on its own at room temperature, but boiling temperature will do it much faster!

Petrol evaporates faster than water at room temperature. this is because the boiling point of petrol is 95oC and water's boiling point is 100oC. As the boiling point of water is higher than that of petrol, petrol evaporates faster as it achieves its boiling point before water does.

it dissolves faster in hot water. than in room temperture. :]
It isn't unusual.
