Boiling point of H20, and it’s influence at density of water
What is the temperature at which water starts boiling? We are sure you know, but as a reminder – the water starts boiling when its temperature is equal to 100 degrees Celsius. There are no doubts that it is a high number! But the temperature is not the only thing which we want to focus on. We mostly want to show you the value of water density at this temperature. What is the density of water lb/ft3 at 100 degrees Celsius? Here is your ready result – the water density is equal to 59.8294 lb/ft3 at a boiling point.
Salt water salinity and variable of density
Do you know that the density of water changes depending on its salinity? Simply put, freshwater, like water which you drink daily, will have a different density than saltwater, like water in the sea. To make this issue clearer, the bigger density will have seawater, not freshwater. How does the value of seawater in lb/ft3 look? Here it is: the density of seawater is equal to 63.9262 lb/ft3. So in comparison with the density of freshwater equal to 62.4264 lb/ft3, the density of seawater is about 1.5 lb/ft3 bigger!
How does water freeze and density changing
You probably know that, in the context of the temperature, there are 2 specific points of water. One of them is the freezing point. Water starts freezing when the temperature reaches 0 degrees Celsius. There are also something like a neutral point which water achieves at 4 degrees Celsius. So it means that the density of water changes at 0 degrees Celsius. How much is the value of density of water in lb/ft3 at the freezing point? This value is 62.421. The basic water density at 4 degrees Celsius is equal to 62.4264 lb/ft3, so these 2 results do not differ significantly as you see.
How to get density of water, it is that hard?
How to calculate the density of water? First thing which you need to understand is the definition of density at all. The density is defined as the mass of water per the volum e of water. So based on it, to calculate the density of water, you should divide the value of the mass by the value of the volume. Theses calculations will allow you to get the result. Of course, to get the result in lb/ft3 you should calculate mass given in pounds and volume given in cubic feet. Remember – if the numbers will be difficult to calculate on your own, you can always use a calculator.
How does actually temperature and salinity affects the density of water
The value of the density of water lb/ft3 depends on a few factors, like the temperature or the salinity, but there is also the basic value. How does it look? The basic value is defined as a value in neutral conditions (freshwater at 4 degrees Celsius) and it is equal to 62.4 lb/ft3. What about such a huge number? Regardless of whether your type was close to the answer or not, one thing is obvious. If you have learned this value, you will learn easily also about other values of density of water in specific conditions.
Could you define density of water now?
Do you want to know the definition of the water density in lb//ft3? To show you the answer you firstly have to see the definition of the water density at all. So how does it look? It is just the mass of a substance by unit volume of this substance. So to sum up, it shows the topic in a descriptive way. There is no legal definition. But let’s get back to the water density lb/ft3. Thanks to the general definition we know that the water density lb/ft3 is the mass determined in pounds per volume determined in cubic feet.
