Therefore, the ρ solid > ρ liquid > ρ gas Solid atoms or molecules are more closely packed together than liquid atoms or molecules. In general, a solid mass of a substance sinks when immersed in a liquid of the same substance. The less-dense stuff floats on top of the dense liquid.īecause the ρwater of ice is smaller than the ρwater of water, ice floats on water. The density of water (g/ml) = 8kg/(8 x10-3 m3 ) The mass (m) of 8 liters of water is 8 kg. Specific weight (γ) = (ρ x volume x g)/volume It is represented by the symbol γ.Īt 4☌, the specific weight of water on earth is 9.807 kN/m 3 = 62.43 lbs/ft 3.Ĭheck the full article “Specific gravity of water”. The specific weight of water is the weight of water per unit volume. There are three different Units of Gallon: Weight of a Gallon of Water Weight of 1 liter (l) of pure water (at 4 ☌) = 1 kilogram (kg). The weight of a gallon of water depends upon storing the temperature of the water, For the sake of the question, ‘How much does a gallon of water weigh?’, we are going to focus on the weight of water at 62 ☏ (17 ☌).ġ US gal of water = 8.345 pounds = 3.785 kg (at 17 ☌).ġ Imperial gal of water = 10.02 pounds = 4.545 kg (at 17 ☌). At 4☌, the density of fresh water on Earth is generally understood to be 1000 kg/m 3. However, this value varies depending on the temperature and impurities in the water.Ĭommon units of ρ water are grams per milliliter (1 g/ml), grams per cubic centimeter ( g/cm 3), and pounds per cubic foot (lb/ft 3). The density of water (ρ water) is around 8.345 lbs/U.S. This is since iron has a greater amount of substance than wood.ĭensity (ρ) formula = mass (m) of substance ÷ volume (v) of substance The density of water in lbs/U.S. We’ll find that iron is heavier than wood.
It is the mass-to-volume ratio of the material. How much does a gallon of water weigh at its highest density?ĭensity refers to the amount of substance per unit volume.The density of Water in g/ml (Effect of Temperature).Calculating the specific weight of water.
