Answer:

#1:

Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.

Answer #2:

Energy is transferred in waves through the vibration of particles, but the particles themselves move in a perpendicular fashion to the horizontal movement of the wave. Energy is transformed between potential (stored) and kinetic (movement) energy as the particles go from rest to movement and back to rest.

Answer #3:

Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. ... The speed of sound is also affected by other factors such as humidity and air pressure.

#5 Answer:

Does air temperature affect the speed of sound? Kim Strong, a professor of physics at the University of Toronto says the answer is yes, in fact sound travels faster when the air is hotter. At 25 C, the speed of sound is 1,246 kilometres per hour.

Answer:

1.When you hit a drum, its skin vibrates. The vibrating drum skin causes neighboring air particles to vibrate, causing other nearby air particles to vibrate as well. A sound wave is made up of these vibrating particles.

2.The vibrating of particles transfers energy in waves, yet the particles themselves travel perpendicular to the horizontal movement of the wave. As particles travel from rest to movement and back to rest, energy is changed between potential (stored) and kinetic (moving) energy.

3.Temperature is another factor that influences sound speed. Heat is a type of kinetic energy, just like sound. Molecules contain more energy at higher temperatures and can vibrate quicker, allowing sound waves to travel faster. Sound travels at 346 meters per second in room temperature air.
