Answer:
the answer is the first one A.
Answer:
Sun protection or a sunscreen
Explanation:
<u>According to Gay-Lussac's Law, also known as the Pressure-Temperature Law:</u> The pressure of a gas confined at constant volume is directly proportional to the temperature.
P ∝ T
Where,
P= Pressure
T= Temperature
<u>In the atmosphere</u>, the temperature is directly proportional to the pressure. It means, if the air pressure rises in an area, the temperature will also increase and vice versa. That's why, if we discover that the pressure is going to rise for several hours in the area, we decided to hike, then we should also choose to pack some sun protection because the temperature is also going to rise.
<u>Atmospheric Relationship</u>
<em>As</em> P ↑ T ↑
<em>As</em> P ↓ T ↓
