Speed of Sound — Prelims Questions

The speed of sound in a gas is $v$. If the temperature of the gas is increased from $27^\circ\text{C}$ to $127^\circ\text{C}$, what will be the new speed of sound?

Which of the following statements about the speed of sound is INCORRECT?

The speed of sound in dry air at $0^\circ\text{C}$ is $331\,\text{m/s}$. If the density of moist air is $0.98$ times the density of dry air at the same temperature and pressure, what is the approximate speed of sound in moist air?

According to Newton's formula, the speed of sound in air at STP is approximately $280\,\text{m/s}$. The experimentally observed value is $331\,\text{m/s}$. This discrepancy was resolved by Laplace by assuming that sound propagation is an:

The speed of sound in a medium depends on:

Two gases, Hydrogen ($H_2$) and Oxygen ($O_2$), are at the same temperature and pressure. If the speed of sound in Hydrogen is $v_H$, what is the speed of sound in Oxygen?
