Air temperature can vary, depending on various factors: not only the altitude, but also lattitude (at the equator it is much hotter than at the poles), the time of day or night, and other factors.
The speed of sound in air has really nothing to do with the sea level and its atmospheric pressure. Speed of sound is dependent on the temperature. Look at the link: "Speed of Sound in Air and the effective Temperature".
The temperature of boiling water at sea level is 100 The temperature of boiling water at sea level is 211.149°F.
The mass of the air would be 984g at 25C (temperature also has an effect).
thermocline is the level in the ocean/sea water that dramatically DECREASES in temperature, and the halocline is the level in the ocean/sea water that dramatically INCREASES in temperature
The speed of sound in air changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary. Look at the link: "Speed of Sound in Air and the effective Temperature":

The speed of sound has neither to do with the sea level nor with Tucson. Speed of sound has mainly to do with the temperature of the air. Look at the link: "Speed of Sound in Air and the effective Temperature".

The approximate dew point at sea level is dependent on more than just the sea level itself. Calculating dew point requires the air temperature as well as relative humidity. So in a general sense, there is no difference in dew point based on elevation if the temperature is the same.
As you get higher above sea level, air pressure decreases. Water boils at a lower temperature when the air pressure is lower. When the water temperature is lower, pasta and anything else takes longer to cook.

At waters boiling point 100 degrees Celsius at sea level. At higher altitudes the temperature is less because there is less air pressure.
Air (especially the air we breath (i.e. near sea level)) does not absorbe the heat from the sun. That passes through the air and is absorbed into the ground (or sea). It's the heat from the ground that heats the air; thus the air nearest the surface of the planet that gets the warmest.
