Answer:
decrease temperature of the oxygen
Explanation:
Answer: The mass density is 1166.36
.
Explanation:
Given: Weight of sample in air
= 500 N
Weight of sample in alcohol
= 200 N
Specific gravity = 0.7 = 
Formula used to calculate Buoyant force is as follows.

Hence, volume of the material is calculated as follows.

where,
= Buoyant force
= specific gravity
g = acceleration due to gravity = 9.81
Substitute the values into above formula.

Now, mass of the material is calculated as follows.

Therefore, density of the material or mass density is as follows.

Thus, we can conclude that the mass density is 1166.36

The horizontal and vertical circulation of ocean waters are known as currents. The main causes of ocean currents include variation in water density, gravity, and wind friction. Surface ocean currents are primarily caused by wind.
