Ques:Q: The amount of water vapor in the air and the temperature of the medium affects how fast what travels? Read this paragraph and choose the correct option from the provided answers: The speed of sound also depends on the temperature of the medium. For a given medium such as air, sound has a slower speed at lower temperatures. You can compare the speed of sound in air at different temperatures in Table below . A lower temperature means that particles of the medium are moving more slowly, so it takes them longer to transfer the energy of the sound waves. The amount of water vapor in the air affects the speed of sound as well. Do you think sound travels faster or slower when the air contains more water vapor? ( Hint: Compare the speed of sound in water and air in Table above . ). Choices: - colour - light - traffic - sound A:

Ans:sound
