Answer:
option (c) 14.7 lbs
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
