This depends greatly upon the temperature the water. At 4oC the density is approximately 1000 kg/m3 (or 1 g/cm3) - more acurately though the density would be 999.97 kg/m3 (or 0.9997 g/cm3).
Values for the density of pure water (H2O) have been calculated over a wide range of temperatures. At room temperature (22oC) The density of water is 997.77 kg/m3 (or 0.99777 g/cm3)

The temperature of the nitrogen at room temperature is whatever the temperature of the room is.
Room temperature IS room temperature, you question makes no sense.
Actinium is a solid at room temperature.
no not all metallic are solid at room temperature.
It doesn't
Hot distilled water would make for a clearer ice cube. It has less entrained gases.
because it just does
Unchlorinated water, such as bottled distilled water is best.
Yes, you can, but it isn't necessary because KMnO4 is fairly soluble in room temperature water.
The room temperature is...the room temperature !!
Salt water
The temperature of the nitrogen at room temperature is whatever the temperature of the room is.
A diamond at room temperature will generally be at the same temperature as the room.
Room temperature IS room temperature, you question makes no sense.
