1.	Q: How does the speed of sound in air changes with a) rise in temperature of air, and b) decrease in humidity in air? (Students have to write weather the given factor will increase, decrease or will bring no change in speed of sound in air).
Answer» PEED of sound waves in air increases with increases in HUMIDITY because air DENSITY decreases with increase in humidity and The speed of sound in a medium is inversely PROPORTIONAL to the square root of its density.
