The oceanographers define salinity by the number of grams of salt per kilogram of water.
Salinity is illustrated as how much salt is present in the given amount of water. It is dependent upon how much salt is found in the ocean in the specific regions. If there is a sunny environment, it may evaporate an ample amount of water, and leave behind a lot of salt, thus, the water has more salinity.
The salinity of the ocean is usually measured in Practical Salinity Unit (PSU), it is a unit based on the characteristics of seawater conductivity.
Answer:
No
Explanation:
A single property is not conclusive for identifying a substance. For example, conductivity. Copper, aluminum, and lead all conduct electricity, yet they have different atomic number, electronegativity, and physical properties, thus their shared property of conducting electricity is not enough to correctly identify each substance.
Answer:
no it is a heterogeneous mixture because salt and pepper are not mixed uniformly.
