1.) The answer would be D.Earth's rotation, since the rotation makes the air and wind direction appear to be going in a different direction than it really is due to the earth rotating (this deflects the winds)
2.) The answer would be C.Relative Humidity, since this is ratio of water vapor in the air to a given area, while humidity is simply the amount of water vapor in the air in general.
3.) B. Warm Front, since cold fronts usually bring stormy weather, while the weather conditions brought by a warm front are typically more mild. 
4.) For this one, I'm not sure, but I'm pretty sure the closest answer would be C.4. The way I have learned this is that there have been 5 major ice ages, however the choice isn't on there.

14. Which of the following is produced when propane (C3H8) is combusted completely? (2 points)
Ymorist [56]

The following is produced when propane (C₃H₈) is combusted completely : H₂O

<h3>Further explanation  </h3>

Complete combustion of Hydrocarbons with Oxygen will be obtained by CO₂ and H₂O compounds.  

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O  

Hydrocarbon combustion reactions (especially alkanes)  \large {\boxed {\bold {C_nH _ (_2_n _ + _ 2_) + \frac {3n + 1} {2} O_2 \Rightarrow nCO_2 + (n + 1) H_2O}}}

For combustion of propane C₃H₈ (n = 3) ⇒ completely(excess O₂) :

C₃H₈+5O₂⇒3CO₂+4H₂O

The products of combustion : CO₂ and H₂O

Compare the first ionization energy of sodium to that of potassium
stellarik [79]

Answer:

Sodium is higher than Potassium in thesame group

Explanation:

Sodium and potassium are the elements present in the first group of the periodic table. In group, atomic size increases from top to bottom this implies that even atomic radius increases. This causes less attraction force by nucleus on the electrons of outermost orbit of the atom and hence reduces the first ionisation energy, which is the energy required to remove the electron from the outermost orbit of an atom. So, as potassium is below sodium in the group, sodium has greater ionisation energy than potassium
