Answer:
●The density of water can also be affected by temperature. When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. This is represented by the increase in the size of the box from Fig.
●Subtract the initial volume of water from the final volume to determine the volume of the metal. Divide the mass by the volume to calculate the density of the metal. For example, if the mass was 7.952 pounds and the volume was 28 cubic inches, the density would be 0.284 pounds per cubic inch.
●Draw a graph of mass of liquid (y-axis) against volume (x-axis). Try to scale the graph so that you can plot all your data sets on a single graph. f For each set of data try and draw a straight 'best fit' line passing through the origin. Calculate the density of each liquid from the gradient of its graph line.
●Destiny Bottles can be spent in the Destiny Bottle Shop, where they can be used to purchase Destiny Gems for 2★ and 3★ Magical Girls. Note that on the NA Server, Destiny Bottles do not carry over from event to event. Once an event store closes all unused Bottles are lost, so it is not possible to save them up.
●Relative density is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material (i.e., water). It is usually measured at room temperature (20 Celcius degrees) and standard atmosphere (101.325kPa). It is unitless.
●because the density of an iron nail is way greater than a wooden cork so cork will float whearas nail will sink.
●Believe it or not, ice is actually about 9% less dense than water. Since the water is heavier, it displaces the lighter ice, causing the ice to float to the top. How is ice less dense than water? ... So for water, the density actually decreases along with a decrease in temperature - causing ice to be less dense than water!
●the density of ice is less than the density of water thus it can easily float on water. ... Since such a large portion of the iceberg is submerged under water it becomes difficult for the sailor to estimate the size of the iceberg increasing the danger of the ship colliding in them.
