Molecules in the air scatter blue<span> light from the sun more than they scatter red light.</span>
Answer:
The atmospheric pressure and boiling point are directly proportional
Increasing atmospheric pressure increases the boiling point also
Explanation:
The atmosphere contain molecules that are in constant motion. They exert a downward force on a liquid’s surface. The higher the air pressure, the harder it is for the liquid to evaporate. Therefore, the boiling point of a solvent or liquid is affected by the atmospheric pressure and boiling point is raised.
A liquid in a high pressure environment boils at a higher temperature.
When placed in a lower pressure environment it boils at a lower temperature.
<span>Usually, If you drop a 200 gram piece of metal with a temperature of 110 degrees Celsius into 1000 grams of water at 25° Celsius, the statement which would best describe what would occur is the last one : </span><span>The water and the metal's temperatures will reach the same temperature. I choose this one because this is a nice example of how the nature tries to reach the balance. Hope it helps! Regards.</span>

Answer:
It would take 1 s to hear the echo.
Explanation:
Here, the sound covered a total of 340 meters, since it bounces off the canyon wall and travels back to Miles in the form of echo.
The time elapsed can be determined by,
v = 
⇒ t = 
where: v is the speed of sound in air (343 m/s), D is the distance of the nearest canyon (170 m).
So that,
2D = 2 x 170 = 340 m
Thus,
t = 
= 0.9913 s
t = 1 s
It takes 1s for Miles to hear his echo.
