In hotter temperatures, The speed of sound would move slower, since the air particles(The medium for sound to travel) would be more spread out in lower air pressure, for colder temperatures, the particiles are more compact, allowing sound to go farther, faster.
The answer to this question is adiabotic process
Answer:
last option is the correct one
According to kinetic molecular theory temperature is a measure of kinetic energy.There is absolute minimum temperature which occurs when something completely stop moving whereby temperature cannot become lower than this point. The absolute zero which has been extrapolated to exist at about -273 celsius while in kelvin scale is set such that absolute zero is 0 k thus kelvin is better inorder to avoid negative number when calculating.
