If the atmospheric pressure is 0.975 atm what is the pressure of the enclosed gas
Nuetrik [128]
Missing in your question:
Picture (1)
when its an open- tube manometer and the h = 52 cm. 
when the pressure of the atmosphere is equal the pressure of the gas plus the pressure from the mercury column 52 Cm so, we can get the pressure of the gas from this formula:
P(atm) = P(gas) + height (Hg)
∴P(gas) = P(atm) - height (Hg)
              = 0.975 - (520/760) 
              = 0.29 atm
Note: I have divided 520 mm Hg by 760 to convert it to atm
Picture (2)
The pressure of the gas is the pressure experts by the column of mercury and when we have the Height (Hg)= 67mm 
So the pressure of the gas =P(atm) + Height (Hg)
                                             =  0.975 + (67/ 760) = 1.06 atm
Picture (3) 
As the tube is closed SO here the pressure of the gas is equal the height of the mercury column, and when we have the height (Hg) = 103 mm. so, we can get the P(gas) from this formula:
P(gas) = Height(Hg)
           = (103/760) = 0.136 atm

Grasslands are a biome that receives 25-75 cm of rain each year and contain what?
s2008m [1.1K]

Answer:

<h3><em>A is most likely your correct answer</em></h3>

Explanation:

A. Hills Covered with dry brush- this is most likely correct

b. Hills covered in lush grass- incorrect, because it is LUSH grass which would require lots of rain.

c. Flat lands with little grass- incorrect because grasslands DO have lots of grass.

D- incorrect because grasslands typically do NOT have rocky mountains <u>but are generally flatlands with grass</u>
