Answer: Option (B) is the correct answer.
Explanation:
It is known that salt water contains high amount of sodium chloride (NaCl).
Also, when it rains then minerals from the rocks are washed or carried away by rain water. Therefore, this rain water passes through various routes and finally reaches to the ocean.
Therefore, the minerals from rocks are deposited in the ocean.
On the other hand, density is defined as mass divided by volume.
Mathematically, Density =
Also, it is known that 1 atmosphere equals 14.69 pound per square inche and not equals to 20 pounds per square inch.
Thus, we can conclude that the true statement is dissolved minerals from rocks are deposited in the ocean.
Surface tension is the property of water which allows for some lightweight insects to walk on top of a pond and not fall in. The molecules of water are held together by cohesive forces. The molecules of water present below the surface experience this cohesive force from all the directions, whereas the water molecules present on the surface experience a downward pull, as the force is not balanced. This leads to the concaving of the water surface inside a small tube.
