Question

How much does the air weigh within a column that is 1 square inch in area that extends from sea level all the way to the top of the atmosphere? Select one:

a. 0 lbs
b. 2.4 lbs
c. 14.7 lbs
d. 29.9 lbs
e. 1013.25 lbs

Answer 1

option (c) 14.7 lbs

Step-by-step explanation:

Data provided in the question:

Area of the column = 1 square inch

Now,

we know Air pressure at the ground surface level from the atmosphere

= 14.7 Psi

also, it can be represented as

14.7 Psi = 14.7 pounds per square inch

Therefore,

Weight of the air weigh within a column that is 1 square inch in area

= Air pressure × Area

= 14.7 pounds per square inch × 1 square inch

= 14.7 pounds i.e 14.7 lbs

Hence,

The answer is option (c) 14.7 lbs
