Statement A: Speed of sound is same at different temperatureStatement ...
Speed of sound is different at different temperature. With increase in temperature, speed of sound increases.
The loudness of sound is measured in units called decibels (dB). A decibel unit expresses the relative intensity of sounds on a scale from zero for the average least perceptible sound to about 100 dB, which is near the level most people find uncomfortably loud.
