Density of Water Experiment
In order to understand more about the density of water, how it behaves, and comparison of it with respect to other substances. Let’s perform the activity mentioned below:
Take a small amount of some liquids that are viscous as water e.g. Liquid Soap, Milk, Sugar Syrup, Honey, Ethyl Alcohol, and Olive Oil in a test tube. Mix them well so that each of the substances cannot be observed clearly.
Now, leave it for a few hours so that the layer of each substance settles down at a certain level as shown below:
Now, it has been observed that different substance has different density This implies each substance weigh differently for the same volume. Because their weight varies, heavier substances tend to settle at the bottom, like honey, and sugar syrup and lighter material like olive oil and ethyl alcohol tends to float at the top.
Density of Water
Density of water is the ratio of the mass and volume of the water at room temperature is 998.2 kg/m3. The density of any substance is defined as the amount of mass present in the unit volume of the given substance.
For pure water, the density is 1 gm/cm3 or 1000 kg/m3. Pure water’s density varies with temperature and reaches its highest point at a temperature of 4 °C, or 1000 kg/m3.
The density of water is maximum at 4 °C.
