Answer:
b the humidity in air incteases
Answer:
(a)
When gas molecules are heated, the molecules move more quickly, and the increased velocity causes more collisions. As a result, more force is exerted on each molecule and air pressure increases. Temperature affects air pressure at different altitudes due to a disparity in air density.
(b)
The water vapor molecules don't travel far after a collision, so they collide more frequently. Therefore, as humidity increases (more water vapor in the air), air pressure decreases, and as humidity decreases, air pressure increases.
(c)
Meteorological Society defines a meteorologist as a person with specialized education "who uses scientific principles to explain, understand, observe, or forecast the earth's atmospheric phenomena and/or how the atmosphere affects the earth and life on the planet." This education usually includes a
(d)
Nitrogen and oxygen molecules collide with other molecules forcefully, whereas the lighter water vapor's collisions are less powerful. ... Therefore, as humidity increases (more water vapor in the air), air pressure decreases, and as humidity decreases, air pressure increases.
The measurements on a barometer are in millibars. NASA shares that normal air pressure at sea level is about 1,013.25 millibars. When there's a hurricane, the pressure can drop down to 30 millibars. Drops in pressure also help indicate the strength of winds in a storm, as greater drops yield stronger winds.
(e)
Nitrogen and oxygen molecules collide with other molecules forcefully, whereas the lighter water vapor's collisions are less powerful. ... Therefore, as humidity increases (more water vapor in the air), air pressure decreases, and as humidity decreases, air pressure increases.
