HW 0 Pre-Course
1 True or False
T F
Temperature usually increases with altitude in the troposphere (the lowest level of the
atmosphere).
T F
Because oxygen (O2
) and nitrogen (N2
) constitute roughly 20% and 80% of our atmosphere,
respectively, an “effective molecular weight” is roughly 29.
T F At 0 C and 1 atm, one gram-mole of an ideal gas occupies approximately 24.2 liters.
T F Air is more dense at low relative humidity. Assume pressure and temperature are constant.
T F Helium is the third most common component of air.
T F In common usage, a westerly wind is one that travels toward the west (i.e., from UMKC to KU)
T F The Coriolis effect is most pronounced at the equator.
T F An acute effect occurs over a short time period.
T F Carbon dioxide is a “criteria pollutant” because it involves climate change.
T F
There are “diminishing returns” in air pollution control, meaning that controlling the first few
tons of a source’s emissions may cost much less than controlling nest few hundred pounds
from the source.
T F The viscosity of air decreases with temperature.
T F
One thousand 1-micron particles have more surface area than a single 10-micron particle.
(Assume all are spherical)
T F President Kennedy established the Environmental Protection Agency/
T F States are primarily responsible for attaining national ambient air quality standards
