a. The skull could support as much as 3 tons of weight.
Explanation:
The true statement about brain is
a. The skull could support as much as 3 tons of weight.
The cranium(skull) bones are slot like a jigsaw puzzle together. All but one of these bones is fixed in place in adults. It makes the skull very solid. Babies have holes between the cranial (skull) bones so that as they are born, their heads may withstand being crushed.
rest all statements are wrong.
Question:
The relative humidity of air equals the ratio of the partial pressure of water in the air to the equilibrium vapor pressure of water at the same temperature times 100%. If the relative humidity of the air is 58% and its temperature is 68 oF , how many moles of water are present in a room measuring 12 ft x 10 ft x 8 ft?
Answer:
15.1379 moles of water are present in a room measuring 12 ft x 10 ft x 8 ft.
Explanation:
Given:
Relative humidity of the air = 58%
Temperature =
To Find:
Number of moles of water are present in a room measuring 12 ft x 10 ft x 8 ft = ?
Solution:
Converting temperature Fahrenheit to Celsius
The vapour pressure of is equal to 17.54 torr
vapour pressure of air
= torr
= 10.17132 torr
Volume of the room =
=>
=>
Using the ideal gas equation
PV = nRT
Volume in Litres = 27184.2 L
Pressure in atm
=
= 0.0133945 atm
Now substituting the values we get
Pv = nRT
n = 15.1379 moles
1/2 - 3/7 = 7/14 - 6/14 = 1/14
