Question

two astronauts are floating in space. Can they talk to each other in space without any device and why?

Answer 1

They can't talk without any device because sound needs a medium to travel and space as we all know is a vacuum. Hence sound waves can't travel leading to the fact that we can't talk in space until and unless we use a special device to do so.
