Question

The weight of air measured in units of force per area is called _____.

A. air viscosity
B. air pressure
C. air resistance
D. relative pressure

Answer 1

The weight of air measured in units of force per area is called air pressure.

Answer 2

B. air pressure

Step-by-step explanation:

The definition of pressure is that it is a force applied to an area.

`P=(F)/(A)`

Because weight is a force (a force is mass multiplied by acceleration, and weight is the product of the mass of an object multiplied by the acceleration of gravity, thus weight is a force), the measurement of the weight of the air over area is the air pressure.

The correct answe is B.
