Sound

Overview: In this lesson you will be learning about sound, the speed in which it moves, the types of gases, liquids, and solids it can move through. This is measured in meters per second or "m/s" for short.
Picture
Gases: Air(0°)
                   Air(20°)
The speed in which sound can be travel through Air(0°)is 331 m/s. The speed in which sound can travel through Air(20°)is 343 m/s
Liquids: Fresh water
                  Salty water
The speed in which sound can travel through fresh water is 1,509 m/s because fresh water has a high mass. The speed in which sound can travel through salty water is 1,546 because salty water has salt in it, giving it a higher mass.
Solids:Lead, plastic, silver, copper, gold, brick, hardwood, cast iron, glass, and steel.
Sound can travel through lead at 1,210 m/s, plastic at 1,800 m/s, silver at 2,680 m/s, copper at 3,100 m/s, gold at 3,240 m/s, brick at 3,650 m/s, hardwood at 4,000 m/s, cast iron 4,480 m/s, glass at 5,170 m/s, and steel at 5,200 m/s.
