Density is a characteristic property of water because the density of any sample of water at the same temperature is always the same.
Thus the density here is 0. This means that the density of a substance is the same regardless of the size of the sample. Another reason is that the density of water changes with temperature. What is the density of Sample C?
Is density a characteristic property of water? MERGE already exists as an alternate of this question. If students do not know what the mass is, tell them that it is half the mass of Sample A.
This means that one litre 1dm3 weighs 1kg. What is the density of Sample B? Tell students that density is a characteristic property of a substance. An empty vial weighs One reason could be inaccuracies in measuring.
Look at your values for density in your chart. Give students time to calculate the density of each of the three samples drawn on their activity sheet and answer the related questions.
A piece of metal displaces 5 ml of water and has a density of What is the density of 50 ml of water? Project the animation Liquid Water. If they are both at the same temperature and both have the same purity, they will both have the same density as density does not depend upon the volume, but the substance itself.
Help students make a graph of the data on their activity sheet. But any way density depends on the temperature. Water molecules are also packed pretty close together.18 rows · Chemistry Department North Carolina State University Density of Water. Get an answer for 'The density of water is g/mL at 4'C.
How many water molecules are present in mL of water at this temperature?' and find homework help for other Science questions at eNotes.
The density of pure water is a constant at a particular temperature, and does not depend on the size of the sample. That is, it is an intensive property. The density of water varies with temperature and impurities. The above table state that liquid water has a mass of 1 g in every ml.
Thus 2 ml of water has a mass of 2 g etc. Table sugar is more dense than water by about 60 percent.
Density does not depend upon size. For example the water in a swimming pool has the same density a glass of that swimming pool water.
The density of water is the weight of the water per its unit volume, which depends on the temperature of the water. The usual value used in calculations is 1 gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm 3).
Water Density. If you are still in school, you've probably heard the statement in the box to the right a number of times: Density. Density is the mass per unit volume of a substance. On Earth, you can assume mass is the same as weight, if that makes it easier.Download
