¿Por qué no hay sonido en el espacio?

The video explains that sound cannot be heard in space because it is a vacuum, lacking the molecules needed for sound waves to travel. On Earth, sound travels through air molecules, and it can also move through liquids and solids. In space, the absence of a medium means sound waves cannot propagate, so no one can hear you scream.

Why can't sound be heard in space, no matter how loud you scream?

• Because space absorbs sound

• Because sound waves are too weak

• Because there are no air molecules to carry the sound

• Because space is too large

What happens when you scream on Earth?

• Your vocal cords produce light waves

• Your vocal cords produce sound waves

• Your vocal cords produce radio waves

• Your vocal cords produce heat waves

What role do air molecules play in sound transmission?

• They block the sound

• They amplify the sound

• They absorb the sound

• They transmit the sound waves

Why is space considered a vacuum?

• Because it has no molecules

• Because it is very dark

• Because it is full of air

• Because it is very cold

What is the result of space being a vacuum in terms of sound?

• Sound travels faster

• Sound is amplified

• Sound cannot travel

• Sound becomes visible
