How and what different factors affect the speed of sound?

Sound
Sound travels in mechanical waves. A mechanical wave is a disturbance. Sound’s speed depends on where it is traveling. Certain factors like temperature affect its speed. Sound travels 5 times faster in water than in air, though travels faster in solid things.
How sound Travels
Sound travels in mechanical waves. ‘’A Mechanical wave is a disturbance that travels through a medium.’’ In sound the disturbance is the abject emitting sound or vibrating.`` A medium is any sequence of connected particles.´´ A human for example, when we talk our vocal cords vibrate. When vocal cords move outward, they push particles of air through the throat. Then those particles push against the air particles near them and so on. Like a domino effect. Sound can also travel in solid surfaces. Sound generally travels faster in solid surfaces than in liquids or gases because the particles are closer together.
Sound will always travel in waves. Some waves differences in pressure and others by moving to the sides of molecules and collapsing with them. One example of this type of wave is movement of the surface of water in a pool. In a solid sound`s speed would vary on the amount an object can compress; the denser the material is the faster sound will travel. In liquids, molecules don`t have a pattern and the bonds break frequently and change their structure. If you raise the pressure in one side it would cause the molecules to move to lower pressure areas and raise the pressure there. Where the pressure was higher at the beginning becomes lower than the average pressure of the liquid. At last the molecules go back to where they started. This happened when you drop a rock into a pond or pool, which is similar to how sound, travels underwater.
Gases are similar to liquids referring to pressure waves. Gases are easier to compress than liquid forms of the substances and also less dense. Sound travels faster in less dense materials, but slower in materials that can be compressed easier.

Speed of Sound
When you are looking at a Launch of a space shuttle you always see it taking of and then you hear it, even if the time between looking and hearing can only be measured with nanoseconds. That is because light travels faster than sound. Some of the factors that affect sound`s speed are temperature and humidity. Sound travels at 1125 feet per second at room temperature.

Conclusion
Sound travels in waves. Light travels faster than sound. Sound can travel in liquid solid or gases. The main factors that make sound faster are: Hot temperatures
