Question

if there is no atmosphere on the moon will astronout be able to speak to each other​

Answer 1

Answer:

No, they are not able to speak, because sound needs a medium to travel. As there is no air or any other thing, for example atmosphere, they can't speak. They talk through the radio signal or walkies

Answer 2

Answer:

There is no atmosphere on the surface of the moon. Since there is no medium in between, the sound cannot travel from one astronaut to the another astronaut on the surface of the moon.
