Heat being transferred in three modes. They are conduction, convection and radiation
As far as conduction and convection are concerned they may be slower than sound
But radiation is by electromagnetic wave. It has the speed of light. So it is not slower than sound.
cause the air has less heat(energy) and will vibrate slower.
sound travels faster through a solid than through air
Yes, but sound travels slower through solids than air.
Faster.
I am not sure what you mean; sound (in air) is actually roughly a million times SLOWER than light.
No, speed of sound in air is much slower than the speed of light in vacuum.
colder air is more dense than warmer air. As a result it is harder for the sound to travel through the cold air and the speed of sound is slower in cold air compared to warm air.
sound waves travel faster slower than light waves In air, sound travels around 300m/s.
No it will move slower. Waves move faster in warm air and slower in cold air.
Sound, in normal air. First lightning then thunder!
No. The denser the material, the faster sound moves through it.
Air sound travels slower when going through a solid object
