Question

The pressure on the windows was generated by air pushing on the windows, which is the average _____ the air molecules are applying over the surface area of the glass.

Velocity
Acceleration
Force
Density

Answer 1

Force

Explanation:

The pressure is defined as the ratio between the force applied on a surface divided by the area of the surface:

$p=\frac{F}{A}$

where F is the force applied and A is the area of the surface.

Therefore, in this specific case, the pressure on the window is generated by the air pushing on the window, and that pressure is given by the average force of the air molecules divided by the surface area of the glass.

Answer 2

Pressure is NOT a Velocity, an Acceleration, a Force, or a Density.

Pressure is the average force per unit area the air molecules are applying over the surface area of the glass.
