Sound travels faster the closer the particles are. Denser material has faster sound.
Sound travels faster in water than in air because water is denser and has a higher elastic modulus. This allows sound waves to propagate more efficiently through water compared to air, where the particles are less tightly packed and have less ability to transmit sound waves.
The speed of sound increases with altitude due to the decrease in air density. This means that at very high altitudes, where air density is lower, the speed of sound will be faster compared to at sea level.
Evaporation is very slow at converting liquid to gas compared to boiling.
It has a very high pitched sound whereas instruments like the Guitar have a very low sound.
I would say it's because sound travels relatively slow, compared to light, etc. it's only about 300m/s. It diffuses as it travels, so the vibrations spread out over a large area and the receiver gets a very vague signal that's close to nothing at all.
Compared to Earth, Mercury has a very fast year. It is 88 Earth days compared to Earth's 365.25 days.
Groundwater flow is very slow compared to currents in surface water, generally moving at less then one and one-half meters per day.
sound is not louder in water because of the water that is in your ears and the sound would be very faint.
density
Compared to molasses, water in the olde mill stream, or traffic on the interstate highway, electric current flows very fast. Compared to the speed of light, in vacuum and in most material media, electric current flows slower.
Sound travels faster through dense objects.
it is slow and not a very specific enzyme
