A) Ocean water is 800 times denser than air.
B) Ocean water is 600 times denser than air.
C) Ocean water is 400 times denser than air.
D) Ocean water is 200 times denser than air.
Correct Answer: A
Solution :
Water has a density of\[1000\,\,gm/{{m}^{3}}\]. The air that is near sea level has a density that averages\[1.275\,\,kg/{{m}^{3}}\]. If we want to know how much water is dense than air that \[1000\,\,kg/{{m}^{3}}\] divided by \[1.275\text{ }kg/{{m}^{3}}\] yields 784. Therefore at the sea level air is 784 time less than the water.
