1. Things that can make a sound

2. Without matter like a solid, liquid or gas, sound could not travel. It needs the vibration of molecules from the matter in order for there to be a sound that can be heard.

1. Sound
2. Throught solids, liquid or gases and can be heard.

1. Everything a person hears is called sound.

2. A sound begins by some type of mechanical movement which can include a person playing an instrument, a door slamming, or thunder in the sky. The molecules of these objects vibrate and in turn cause the surrounding molecules to vibrate, thus causing the sound to travel

1. Description about sound.
2. The sound have travel through solids, liquids, or gases and can be heard

1.sound
2.Through solids, liquids, or gasses and can be heard.

3.3. A sound begins by some type of mechanical movement which can include a person playing an instrument, a door slamming, or thunder in the sky.

3. What are the examples of mechanical movement?
Answer : Some type of mechanical movement which can include a person playing an instrument, a door slamming, or thunder in the sky.

4. How do you compare the sound speed in water, air and steel?
Answer : Sound will travel faster in water than in air, but much faster in steel. The amount of moisture in the air will also affect the speed of sound. In dry air, sound will travel 768 miles per hour, but faster in water. At 768 mph, sound will travel one mile in 5 seconds through dry air, but four times faster in water, and 13 times faster through steel.

The best title for the passage is sound

3. mechanical movement which can include a person playing an instrument, a door slamming, or thunder in the sky.

3. The sound is initiated by some type of mechanical movement which can include someone playing an instrument, slamming a door, or thunder in the sky. The molecules of these objects vibrate and in turn cause the surrounding molecules to vibrate, causing the sound to move.
Decibels are used to measure loudness. The more decibels, the louder the sound. A whisper can only produce 15 to 20 decibels, but a jet engine can produce 150 decibels

3. a person playing an instrument, a door slamming, or thunder in the sky
4. In dry air, sound will travel 768 miles per hour, but faster in water. At 768 mph, sound will travel one mile in 5 seconds through dry air, but four times faster in water, and 13 times faster through steel.

Medium : no less and no more, not big and not small
Sound barrier : the increased drag, reduced controllability, and other effects that occur when an aircraft approaches the speed of sound, formerly regarded as an obstacle to supersonic flight.
Sonic boom : a loud explosive noise caused by the shock wave from an aircraft travel faster than the speed of sound.
Acoustics : associated with hearing, sound or sound science

5.The solid, liquid, or gas that transports the sound is called a (medium).
When this happens, the plane breaks the (sound barrier).
They also create a (sonic boom), which is a loud explosive- sounding noise that is caused by a number of sound waves that are forced together as the plane moves faster than sound.
(acoustics) is the study of sound and how it travels.

5. A. Medium is Outer space is void of any objects and is a vacuum so there is no sound and it is very quiet. The solid, liquid, or gas that transports the sound.
B. Sound barrier is often heard when airplanes go faster than the speed of sound.
C. Sonic boom is which is a loud explosive- sounding noise that is caused by a number of sound waves that are forced together as the plane moves faster than sound.
D. Acoustics is the study of sound and how it travels. Someone specializing in acoustics learns how sound moves, which is important when building auditoriums, theaters, and other types of buildings
