| Question | Answer |
|---|---|
| Air pressure depends on | Mass of the molecules & kinetic molecular energy |
| Dalton's Law states: | Total pressure exerted by mixture of gases is sum of pressures produced by each constituent gas |
| In general, the weather becomes stormy when air pressure_____ but clears or remains fair when air pressure ______ | falls......rises |
| According to Avogadro's Law, the greater the concentration of water vapor, the air becomes | less dense |
| Which air masses are the densest and thus produce higher surface pressures A) Cold, dry B) Cold, wet C) Warm, dry D) Warm, wet | Cold, dry |
| What influences air pressure? | Local conditions and air mass advection |
| Differences in air pressure create | Horizontal pressure gradients |
| What causes cold or warm air advection? | Pressure gradients |
