Which statement about atmospheric pressure is false?

A) The warmer the air, the lower the atmospheric pressure.

B) Atmospheric pressure prevents water in lakes, rivers, and oceans from boiling away.

C) As air becomes thinner, its density decreases.

D) With an increase in altitude, atmospheric pressure increases as well.

E) Air actually has weight.

D) With an increase in altitude, atmospheric pressure increases as well.

Explanation:

Generally when altitude increases, the value of pressure decreases. This shows that pressure is inversely proportional to altitude. For example, the higher the altitude, the lower the pressure and vice versa. At very high altitude, the number of molecules of air are smaller than the number of moles of air at very low altitude. Thus, the higher the altitude, the lower the atmospheric pressure and the lower the altitude, the higher the atmospheric pressure. Therefore, option (D) is false.
