depends if you are talking about a forced gas such as a high pressure nozzle blowing the gas out or diffusion of a gas into the air, the first depends on pressure, the second depends on heat
Sound travels through each medium (and each gas) at different velocities.In air, sound travels at an approximate speed of 330 m/s.Factors such as temperature and humidity also affect the speed of sound.
Air is gas.
. . . decreases.
Speed of sound travels in gases (like air), in liquids, and in solids. In air at 20 °C speed of sound travels with c = 343 m/s.
Of course not,it is not true. The speed of light decreases
Gas travels up and destroys the atmosphere therefore air gets out :(
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
The speed is the same. Light travels at a finite speed.
The speed of light, which is about 300,000,000 m/s, can be affected by the material that it is travelling through. Mediums such as air, glass, and water can slow light down. For example, in water, light travels at a speed of about 200,249,000m/s; in ammonia gas, it travels at 221,200,000m/s; and in ethanol, it travels 220,400,000m/s.
A 747 typically travels about 600mph.
It travels at the same speed.
No. Speed depends on how dense the material is that the sound travels through- it travels faster in dense water than in light air. The VOLUME of the sound has no bearing on the speed that it travels.
