What would happen to sound waves created when a star explodes (supernova) in space?

• The sound waves will move faster through space and then slow down as it enters the Earth's atmosphere.

• The wavelength of the sound wave would decrease as it travels through space and then it will increase as it moves into the Earth's atmosphere.

• The wavelength of the sound wave would increase as it travels through space and then it will decrease as it moves into the Earth's atmosphere.

• The sound waves will not travel through space because sound must have a medium to travel through.

Typically, sound will travel fastest in a –

• Liquid

• Plasma

• Gas

• Solid

Why do sound waves travel faster in warmer air compared to colder air?

• The air particles move faster and collide more often in warmer air.

• The air particles are closer together in warmer air.

• The air particles are more elastic in warmer air.

• The air particles carry more energy in colder air.
