Question

sound waves to travel faster through a low-density gas (such as helium) or a higher-density
gas such as carbon dioxide? Justify your answer based on what you have learned. (short simple answer pls)

Answer 1

Sound waves travel faster in lower-density gases, such as helium, compared to higher-density gases like carbon dioxide. This is because the speed of sound is influenced by the mass of the gas particles; lighter particles (like those in helium) can transmit sound waves more quickly than heavier particles (like those in carbon dioxide). Therefore, sound waves propagate faster in helium.
