20. What scientific law best explains the compression and heating of air during the Santa Ana winds? Charles's Law Boyle's Law Combined Gas Law C Gay-Lussac's Law

## Step 1<br />The Santa Ana winds are a type of wind that is characterized by high temperatures and low humidity. This is due to the air being compressed and heated as it descends from higher elevations.<br /><br />## Step 2<br />The Combined Gas Law is the scientific law that best explains this phenomenon. The Combined Gas Law combines Charles's Law, Boyle's Law, and Gay-Lussac's Law. It states that the ratio of the product of the volume and pressure of a gas is equal to the product of the absolute temperature of the gas and a constant.<br /><br />### **The Combined Gas Law: \( \frac{P \cdot V}{T} = k \)**<br /><br />## Step 3<br />In this case, the volume of the air is decreasing (as it descends), the pressure is increasing (due to the compression), and the temperature is also increasing (as the air is being compressed and heated). This is consistent with the Combined Gas Law.
