Question 7Speed of Sound Through Different MaterialsMaterial Approximate Speed (m/s)Air (20°C)      350Glass   5,600Steel   5,900Water (25°C)   1,500Rubber   1,600Diamond 12.000Iron   5,100 Based on the figure shown, sound waves travel most slowly through which of the following?Multiple choice question.A)airB)glassC)rubberD)water

Brianna and Roger were conducting an experiment that involved sending sound waves through different materials. When the pair organized their data, they discovered that there was a pattern to the speeds the sound waves traveled. What can change the speed of sound through a material? Choose the two that apply. A. mass B. temperature C. length D. width E. density

6. The more dense a liquid becomes, the faster sound travels in it. The data in the table below show the speeds at which sound travels in different liquids:

The speed of sound is dierent in dierent media. For example, in water it is ~1500 m/s. Draw a model to explain why sound propagates faster in water. Based upon your model, predict whether or not the speed of sound would be faster or slower through a wooden door than water.

Which of the following properties is NOT a factor to determine the speed of sound?Aelasticity BtemperatureCfrequencyDdensity
