Does sound travel faster through air 0 C or through seawater?
Sound Propagation in Sea Water
The speed of sound in sea water is on average about 1560 m/s or 3490 mph. Compare this to the speed of sound in air which is 343.2 m/s. The discrepancy is obvious: sound travels nearly five times faster in seawater than in dry air!
What is the speed of sound in air?

The speed of sound in dry air at 22 °C is 344.632 m/s.
What is the speed of sound in room temperature air?
What is the speed of sound in air of 15 Celsius?
At 15 degrees C the velocity of sound is about 340 m/s in air and 997 m/s in helium gas.
Does pitch affect the speed of sound?
The speed of sound is dependent on temperature. As the temperature of the air increases the speed of sound in air increases. … Frequency of sound and pitch are related. The higher the pitch the greater the frequency.
Can sound travel in a vacuum quizlet?
Sound cannot travel through a vacuum because it needs matter to vibrate and travel through. … Molecules are closest together in solids so sound travels most quickly through this medium. As the distance between molecules increases the speed of the sound wave decreases.
Does sound travel faster in warm air than in cold air quizlet?
It depends on wind conditions temperature and humidity not on loudness and frequency. All sounds in the same medium travel at the same speed. … Faster in warm air faster in humid air.
How do you find the speed of sound in air with temperature?
In air the speed of sound is related to air temperature T by vw=(331m/s)√T273K v w = ( 331 m/s ) T 273 K . vw is the same for all frequencies and wavelengths.
Why is sound faster in seawater?
Sound and Salinity
In seawater sound travels up to 33 meters per second faster than in freshwater. … Sound travels faster in the ocean because there are more molecules — specifically salt molecules — for waves to interact with as well as higher surface temperatures.
What is the speed of sound in air and water?
The speed of sound in air under typical conditions is about 343 meters per second while the speed of sound in water is about 1 480 meters per second.
Is the speed of sound faster in air or water?
While sound moves at a much faster speed in the water than in air the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.

What is the speed of sound in air at 100 C?
When the temperature is increased by 10 C the speed of sound is?

What is the speed of sound at 36000 feet?
the temperature is 59F and Mach 1 is approximately 761 mph. As the altitude increases the temperature and speed of sound both decrease until about 36 000 feet after which the temperature remains steady until about 60 000 feet. Within that 36 000? 60 000 foot range Mach 1 is about 661 mph.
Who fast is Mach 1?
What is the speed of sound in air increases by?
How does amplitude affect sound?
The larger the amplitude of the waves the louder the sound. Pitch (frequency) – shown by the spacing of the waves displayed. The closer together the waves are the higher the pitch of the sound. … So sounds 2 and 3 are the same volume (amplitude) but 3 has higher pitch (frequency).
How does the speed of sound depends on its amplitude?
Amplitude and sound are directly proportional. The amplitude of the wave determines the loudness of a sound wave. A larger amplitude means a loud sound while a smaller amplitude means a soft sound. If the amplitude is high then the sound will be louder and the sound will be feeble if the amplitude is low.
