- At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml,
1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft
- At 4°C pure water has a specific gravity of 1. ( Some reference the s.g. base temperature as 60F.)
- Water is essential for life. Most animals and plants contain more than 60 % water by volume.
- More than 70 % of the Earth's surface is covered with about 1.36 billion cubic kilometers of water / ice
- The density of pure water is a constant at a particular temperature, and does not depend on the size of the sample. That is, it is an intensive property. The density of water varies with temperature and impurities.
- Water is the only substance on Earth that exists in all three physical states of matter: solid, liquid and gas.
- When water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified. As ice is lighter than water, it floats.
- Water has a very simple atomic structure. This structure consists of two hydrogen atoms bonded to one oxygen atom - H2O
- Note; kg/m3 divided by 16.02 = lbs/cu.ft. kg/m3 divided by 1,000 = g/ml
Convert g/cm3 = g/cc = g/ml = g/mL - they are all the same.

Is water a protein?
what is the relationship between body proteins and water? what is the relationship between body proteins and water?
What is the relationship between a dam and a reservoir?
The relationship between a dam and a reservoir is that they both hold water.
What is the relationship between density and temperature?
Due to thermal expansion, as temperature increases, density decreases.There is no simple relationship. Usually, but not always, if a substance is heated, it will expand, thus decreasing its density.
What is the relationship between specific heat and the change in temperature of a substance?
Specific heat is the amount of energy it takes to raise a unit mass of the substance by one degree Celsius. For each unit of specific heat applied to a substance its temperature will increase by a set amount.
What is the relationship between pressure and heat?
Heat is the movement of energy in response to a difference in temperature. Heat flows in a direction from high to low temperature, and has the effect of tending to equalize the temperatures of the objects in thermal contact. Thus the flow of heat may raise the temperature of one object while lowering the temperature of the other. A more appropriate question would be, what is the relationship between pressure and temperature? This in itself is still an ill-posed question (it depends on what is held fixed, e.g., the volume, while the temperature is changed), but in a general sense the pressure will increase with temperature (although there are notable exceptions, such as water near freezing).
Is the relationship between the temperature of water and the solubility of a gas in it a direct or inverse relationship Explain?
The temperature of water and the solubility of a gas are in an inverse relationship; gases are more soluble at low temperatures.
What is the relationship between the triple point of water and the si unit for temperature?
kkk
What is the relationship between an ocean's temperature and slinity?
it is how much salt mass in the ocean water
What is meant by equilibrium sorption isotherm?
it is a relationship between moisture content & water activity in a constent temperature
State the relationship between water temperature and the maximum mass of ammonium chloride that can be dissolved in 100 grams of water?
As the temperature of the water increases, the amount of solute (in this case NH4Cl) that can be dissolved increases.
What is the relationship between water temperature and plant growth?
Water temperature can majorly change how a plant grows. Too cold or too hot water can make a plant not be able to grow at all.
What is the relationship between temperature and time for water between -5degrees and 100 degrees Celsius?
None, since there is no information about time in the question.
What is the relationship between latitude and sea surface temperature?
The oceans surface water temperature varies with the amount of solar radiation received, which is primarily a function of latitude.
How does pressure affect the temperature at which water boils?
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
What is the relationship between the temperature and dew point?
Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
What is the relationship between temperature air molecules and water vapor?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
What is the relationship between water vapor air molecules temperature?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
