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 Gay-Lussac's Law

## Step 1<br />The Santa Ana winds are a phenomenon where warm, dry air descends from the high-pressure areas in the interior of the western United States and blows towards the coast of California. This warm air compresses and heats up as it descends, which is a characteristic of Gay-Lussac's Law.<br /><br />## Step 2<br />Gay-Lussac's Law states that the pressure of a gas is directly proportional to its absolute temperature, provided the volume is kept constant. This means that if the volume of the gas is constant, an increase in temperature will result in an increase in pressure.<br /><br />## Step 3<br />In the case of the Santa Ana winds, the volume of the air is constant, but the temperature increases as the air descends. This increase in temperature leads to an increase in pressure, which is the characteristic of Gay-Lussac's Law.
