It is about 72 degrees F. if the temperature in the room is 72 degrees F. In other words, water at room temperature is generally somewhere near the temperature of the room.
about 25 degrees. this web site is crap cause it took me for ever to find the answer to this question and i didnt even find the answer on this web site.
Assuming the water hasn't just come from the fridge, it will take on the temperature of the room, which will be on average 18-21oc.
hot oil.
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.
Density: Mass/volume , so it is obious that density will changed with increase in temperature as volume is proportionaly changes with temperature so density will be decreases with increase in temperature. From this stand point we can say hot water has lower density then the water which is kept in room temperature. In 4'C water has higher density than other temperatures.
Flour is not dissolved in water, excepting some minor components.
This depends on the volume and temperature of the water. Assuming we're talking about a glass of room temperature water, the ice cube should melt more quickly if left out of the water. This is because as the cube melts, it has a greater effect on cooling the temperature of the water than it would the air in a room.
hot oil.
Hot water would take longer to reach the freezing point than room temperature so hot water would freeze slower than water at room temperature
it dissolves faster in hot water. than in room temperture. :]
Water molecules have more space between each other in cold room temperature than hot water.
Hot distilled water would make for a clearer ice cube. It has less entrained gases.
They dissolve faster in hot water.
Yes
Assuming you mean for plants, think "rain temperature." Not hot, but room temperature to slightly cooler than that.
It depends on how hot/cold your water is, and how hot/cold room temperature is.

There is no such thing as hot ice. The ice is a cold and frozen solid made out of water. Ice happens when water freezes at 0 degrees Celsius. But if the ice is hot, it will turn into water. If you touch the top of fridge it most of the time hot or at room temperature, so the water(hot ice as you said it) will remain at the same temperature as the room or hot.
