Is it true that sound moves faster in air that is 90 degrees Fahrenheit than in air that is 32 degrees Fahrenheit?

No. Sound moves faster in a denser medium and the colder the air is the denser it is.

What is the speed of voice per minute?
In common everyday speech, speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance. Sound travels faster in liquids and non-porous solids than it does in air. It travels about 4.3 times faster in water (1,484 m/s), and nearly 15 times as fast in iron (5,120 m/s), than in air at 20 degrees Celsius.
What does the term supersonic mean?
The simple answer is "Faster than the speed of sound"
How many miles per hour is mach 8?
Mach is not an absolute speed but a relative speed. The Mach value of an object is the ratio of the speed fo the object travelling through a medium to the speed of sound travelling through the same medium. Now sound travels faster in denser mediums so the speed of sound in [dense]air at sea level is greater than the speed of sound at high altitude. So Mach 2 in the air at sea level is faster than Mach 2 at high altitude. But Mach 2 under water is very much faster. However, most people are ignorant about the proper meaning of Mach and assume that it is simply related to the speed of sound at sea level at normal temperature/pressure/humidity - approximately 760 miles per hour. In that case Mach 8 would be 6080 mph.
A rock is dropped from a sea cliff and the sound of it striking the ocean is heard 3.8s later If the speed of sound is 340 ms how high is the cliff?
The sound moves in a second 340 metres. That is in 3.8 seconds 1292 metres. But because there is the way down to the ocean and back to the ears of the stone dropper, the distance must be half of it. The cliff is 646 metres high.
What speed is mach 8?
Mach 1 is the speed of sound, which is 343 meters per second, or 343 m/s. Mach 8 is 8 times faster than the speed of sound . 8 X 343 2,744 m/s or 2.74 km/s
What happen to the speed of sound as it moves from water to air?
It will slow - sound moves faster in water than in air.
What is the speed of sound at 70 degrees Fahrenheit?
The answer depends on what the medium is!
Do sound waves travel fast?
Depends on what they are traveling through- the denser the substance, the faster sound moves. It travels faster through water than through air. In air, the greater the air pressure, the faster it moves (denser air). The lower the temperature, faster the speed (cold air is dense). At sea level, 20 degrees Celsius, sound travels through air at 1126.547 ft/second- or about 768.095 mph

Is the speed of sound in cork greater than speed of sound in water?
No. The denser the material, the faster sound moves through it.
How to get gass out of supbeans?

What moves faster in solids than in liquid?
Sound will usually move faster in a solid than in a liquid.
Why the flash of the gun reaches as before the sound of the gun?
Because light moves substantially faster than sound.
What is heard when something moves faster than the speed sound?
You hear a sonic boom
Will sound travel faster in 58 degrees Celsius or 88 degrees Celsius?
58 degrees because it is closer to 69 degrees.
Which travels faster sound at 15 degrees Celsius or 30 dgrees Celsius?
what
Why does sound move faster through stone than water?
sound moves faster though stone than water because stones particles are closer together and vibrate faster. +++ We can add that in general, the denser the material the higher the speed of sound through it.
