Only in the metric system. The metric system bases its unit of weight, the gram, on the weight of one millilitre of water. Therefore one litre of water (or other liquid which is mostly water) weighs one kilogram (1000 grams)
The weight of the rock will be lessened by the weight of the same volume of water. If the rock weighs less than that volume of water, it will float (as does pumice). Thus, if you had a rock that has a density (weight/volume) of 2 times the same volume of water, it would weigh one half of its dry weight when in water.
WATER
The difference between an object's weight, and the weight of water with the same volume as the object.
It is not. It varies slightly. The volume of ice will be larger than with water when water and ice are the same weight.
The weight of eggs, water and milk are measured in ounces or cups. The volume of water, eggs, and milk is measured as a liquid. The volume of butter is measured as a solid.
Yes, the weight is 20 ounces, however the volume will be different
they share the same volume. In the Metric system, Liters are a measurement of volume, not of weight. Therefore, 10 Liters of water would share the same volume as 10 Liters of Mercury.
They are the same volume and very close to the same weight.
Yes, in respect of samples of wood and water with the same weight. Before you put the wood in the water, the bulk of the water is supporting a volume of water at the surface, whose shape is the same as the submerged part of the wood. Wood has a lower density so the weight of the wood below the surface is lower than the weight of the water it displaced, and the weight of the wood above the surface makes up the difference, so the water is supporting the same total weight as before.
Density is weight divided by volume. Since the size of the hull stays the same, when the weight of the water is removed, the volume of the hull stays the same and the density is reduced.
Of what? There is no universal correlation between volume and weight. 24 ounces of water IS NOT the same volume as 24 ounces of sugar.
Archimedes principle states that a floating body displaces its own weight of water. The density of the water is fixed so the volume displaced by a floating body is is the same for floating bodies of the same weight. The water level will still be delta h1 as the volume of the block is not relevant to the amount of water displaced.
