Sound will travel on any planet with an atmosphere. The speed of sound depends on the density of the material it is passing through - the more dense, the faster it travels. Try listening to sounds underwater sometime.

Any planet covered by a fluid will have a speed of sound. Because of evaporation, any planet covered with liquid will have an atmosphere, so we need consider only the speed of sound in a gas. This speed is inversely proportional to the molecular weight of the gas, and directly proportional to the square root of the absolute temperature, so can be calculated if you know the temperature and composition of the atmosphere. Note that the speed does NOT depend on the density.

As long as the planet has a medium through which sound can travel, yes (usually an atmosphere, but sound can travel through any medium except a vacuum). And the speed at which sound travels depends on both the medium and temperature (I can't remember if heat speeds or slows sound). The sound barrier is broken when the speed of an object traveling through a cetain medium is faster than the speed of sound in that medium.

It all depends upon how dense the atmosphere is and what it's made of. The "sound barrier" is when an object travels through the atmosphere faster than the atmosphere can propagate a sound wave and sound waves travel at different rates according to the medium through which they are traveling.

The sound barrier is the speed sound travels through a medium. Technically every medium has a sound barrier if, for instance, it is 1 m/s, then for every multiple of 1 there will be a sonic boom. Of coarse, the higher the barrier, the higher the energy of the "boom".

The sound barrier on earth is in flux and depends upon the density of the atmosphere. Study kevlar laws and pressure volume etc....I thought kesslar than thought planc and i used planks when I built houses out of whiskey laws
My sense of humour though twisted by the laws of the universe is still clean.
