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 resumed answer pls)

Answer 1

Sound waves travel faster in low-density gases like helium compared to higher-density gases like carbon dioxide. This is primarily because the speed of sound is influenced by the gas's density and temperature. In general, sound travels faster in lighter gases because the molecules can transfer the kinetic energy of sound waves more efficiently. Helium, being less dense, allows for quicker molecular motion and faster transmission of sound waves than the denser carbon dioxide.
