That gallon of tap water at 70F weighed 8.329 pounds, which was a lot for a 70-pound kid to haul up a huge hill. Surroundings and that the water and the other us the salinity of the water and the other us the of! The density of water is most given as 1 g/cm3, but below is the density of water with different units. If the substance you're trying to find the density of is a liquid, you can simply pour the liquid into the graduated cylinder and see what its volume is, then calculate density from there. This is permalink. In the Imperial system the mass unit is the slug [sl], and is derived from the pound-force by defining it as the mass that will accelerate at 1 foot per square second when a 1 pound-force acts upon it: 1 [lbf] = 1 [sl] * 1 [ft/s2] and 1 [sl] = 1 [lbf]/1 [ft/s2], The density of water is 1.940 sl/ft3 at 39 F (4 C), and the specific weight in Imperial units is, = 1.940 [sl/ft3] * 32.174 [ft/s2] = 1.940 [lbf]/([ft/s2]*[ft3]) * 32.174 [ft/s2] = 62.4 [lbf/ft3], See more about the difference betweenmass and weight. & sg of pure & tap water, Feet to metres The definition of density, makes a lot more sense with a little bit of explanation. (a) What is the mass of the gold ring? 4 How to calculate the density of a sample of water? Water has a high specific heat capacityit absorbs a lot of heat before it begins to get hot. The best way to visualize how water can have different densities is to look at the frozen form of water. This is why ice floats on top of water and, when you put ice cubes in a glass of water, they don't just sink straight to the bottom. 0.9970 g/mL Example of relatively small density is styrofoam, . A common unit of measurement for water's density is gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm3). Looking at water, you might think that it's the most simple thing around. This is not a surprise, but actually almost all of the volume of an iceberg is below the water line, not above it.
