Answer:
880 kg / m^3
Explanation:
height of column of oil = 85 cm = 0.85 m
height of column of mercury = 5.5 cm = 0.055 m
Density of mercury = 13600 kg/m^2
Let teh density of oil is d.
A the height of mercury column is balanced by the height of oil column
So, the pressure due to the mercury column = pressure by teh oil column
height of mercury column x density of mercury x g = height of oil column
x density of oil x g
0.055 x 13600 x g = 0.85 x d x g
748 = 0.85 d
d = 880 kg / m^3
Answer:
Relative humidity depends on the amount moisture actually in the air at some temperature to the amount of moisture that the air can hold.
For instance, at 25 deg C the air has a saturation pressure of 23.76 mm of Hg.
That means that if at that temperature the pressure of the water vapor in the air reaches 23.76 mm Hg then the air is 100% saturated.
I believe the standard air pressure at 25 deg C is 760 mm Hg.
Now if the pressure of the water vapor in the air is 1/2 * 23.76 = 11.88 mm then the air is 50% saturated and the relative hunidity is 50 %.
At 100% relative humidity rain occurs (the air can't hold any more water).
