1. The speed of sound in air is affected by changes in which of these factors?

Its moisture content, its temperature, and the composition of the air

Atmospheric pressure alone, holding temperature fixed

Only the temperature of the air

Only the composition of the air

Sound speed in air depends on moisture content, temperature, and the gas composition — all of which affect the air’s density or elasticity. At a fixed temperature, pressure alone does not change sound’s speed.
