The Mars rover Perseverance has measured the speed of sound on Mars and it’s about 100 m/s slower than the speed of sound on Earth..
Could you speak up..
Did you know - A balloon’s pop is caused by the rubber shrinking faster than the speed of sound..
Yeah makes sense. The air is less dense..
Actually no. Density has almost no effect on speed of sound. Otherwise everyone would have higher voices in Denver Colorado where pressure is only 85% of sea level pressure. It will be down to different temperature and composition of the Martian atmosphere..
Density affects the efficiency of propagation, not the speed. Zero density=zero propagation..
Oh never mind .
Have a balloon .
