PROBLEM 30P

The pressure on top of Mount Everest averages about 235 mm Hg. Convert this pressure to:

(a) Torr

(b) pounds per square inch

(c) inches of mercury

(d) atmospheres

Solution 30P

Here, we are going to convert the given pressure to different units.

Step 1:

Given pressure = 235 mm Hg

Converting mm to inches, we get,

25.4 mm = 1 inch

Therefore, 235 mm = (1/25.4) x 235 inches

= 9.25 inches

Thus, 235 mm Hg = 9.25 inches of mercury.

Step 2:

Now, 760 mm Hg = 1 atm

Therefore, 235 mm Hg = (1/760) x 235 atm

= 0.309 atm.

Thus, 235 mm Hg = 0.309 atmospheres.
