Apr 18, 2014 · The maximum density of water occurs at 4 °C because, at this temperature two opposing effects are in balance. > In ice, the water molecules are in a crystal lattice that has a lot of empty space. When the ice melts to liquid water, the structure collapses and the density of the liquid increases. At temperatures well above freezing, the molecules move faster and get further apart. The density ...
Nov 5, 2015 · The denser the water, the less light reaching those animals living deeper in the ocean, causing different specializations to adapt to that. The denser the water the less light that can get through to the bottom of the ocean. Fish also have to adapt to this in order to survive and hunt their prey. Some have evolved huge eyes that can see better ...
Nov 3, 2015 · 1 Answer. Bio. Nov 3, 2015. Density of ice is less than the density of water. Therefore lakes freeze top down in the winter. Explanation: Ice floats because it is less dense than water. Therefore, during the cold season, a layer of ice will form on the surface of ponds and lakes, creating an insulation for the aquatic lives underneath.
Aug 7, 2014 · So the denser the fluid is, the greater the buoyancy and the buoyant force. Example: An average 25-year-old adult male with a mass of 70 kg has a density of 1.06 kg/dm³. His volume is V = 70 kg × (1"dm³")/ (1.06"kg") = 66 dm³ Since the density of water is 1.00 kg/dm³, the person displaces 66 kg of water. The buoyant force of the water is ...
Jul 10, 2017 · Jul 10, 2017. Density Plays an Important role in water cycle as :-. The Water Vapours have low density and so they rise up and later condenses to form clouds. When precipitation ( Raining ) occurs , the water droplets have more density and so they fall towards gravity. Answer link.
Density is the amount of matter in an object compared to its volume (the amount of space it takes up). If an object were extremely dense, it would feel heavier than another object of the same size that was less dense. For example, a 1-litre soda bottle filled with air would feel much lighter than the same bottle filled with water. Water has a density of 1 kilogram per liter, while air has a ...
Physics. Water (density = 1.0 x 103 kg/m3) flows through a horizontal tapered pipe. At the wide end its speed is 4.0 m/s. The difference in pressure between the two ends is 4.5 x 103 Pa. The speed of the water at the narrow end is: 2.6 m/s 3.2 m/s 4.0 m/s 4.5 m/s 5.0 m/s. Water (density = 1.0 x 103 kg/m3) flows through a horizontal tapered pipe ...
Jun 2, 2018 · Explanation: density (ρ) that is the ratio between mass and volume is present in Reynold's number. Re = ρ × d × v μ. and its increasing, increase the possibility to have a turbolent flow (when Re > 4000) To move the fluid you have to give electric power according to the relation: N = F × H η. where N is the Power. H is the prevalence.
Mar 2, 2017 · Explanation: Density is a so-called intensive property, whose magnitude does not depend on the size of the system. For a given temperature, thus 10 ⋅ kg of water has the same density as 1 ⋅ kg of water: Density, ρ = Mass Volume. ρ1 = 10 ⋅ kg 10⋅ L = 1 ⋅ kg ⋅ L−1 or 1 ⋅ g ⋅ cm−3. ρ2 = 1 ⋅ kg 1 ⋅ L = 1 ⋅ kg ⋅ L−1 ...
Physics. Water (density=1.0gcm3) rises in a glass capillary tube to a height of 8.4 cm at 25∘C. What is the diameter of the capillary tube? The surface tension of water is 0.07199 kgs2. Water (density=1.0gcm3) rises in a glass capillary tube to a height of 8.4 cm at 25∘C. What is the diameter of the capillary tube?
