The speed of sound is generally faster in solids than in gases, because solids are denser than gases. The speed of sound is generally faster in solids than in gases, because solids are less dense than gases. The speed of sound is generally faster in solids than in gases, because solids are less dense than gases. The speed of sound is generally slower in solids than in gases, because solids are denser than gases. The speed of sound is generally slower in solids than in gases, because solids are denser than gases. The speed of sound is generally slower in solids than in gases, because solids are less dense than gases. The speed of sound is generally slower in solids than in gases, because solids are less dense than gases. Question 2 A)The speed of sound through diamond is about 12,000 m/s. The speed of sound through wood is about 3,300 m/s. Which statement explains why the speed of sound is different through these materials?(1 point) Responses They have different temperatures. They have different temperatures. They have different rigidities. They have different rigidities. They have different salinities. They have different salinities. They have different phases of matter. They have different phases of matter. Question 3 A) The table below shows the speed of sound in water at different temperatures and salinities. The table shows the speed of sound in freshwater and seawater at different temperatures. Temperature (°C) Speed of Sound in Fresh Water (m/s) Speed of Sound in Sea Water (m/s) 0 1403 1449 10 1447 1490 20 1481 1522 30 1507 1546 Based on the table, which statement describes the relationship between temperature and the speed of sound in water? (1 point) Responses Sound travels faster in warmer water, but this occurs only in fresh water. Sound travels faster in warmer water, but this occurs only in fresh water. Sound travels slower in warmer water, but this occurs only in fresh water. Sound travels slower in warmer water, but this occurs only in fresh water. Sound travels faster in warmer water, both in fresh water and sea water. Sound travels faster in warmer water, both in fresh water and sea water. Sound travels slower in warmer water, both in fresh water and sea water. Sound travels slower in warmer water, both in fresh water and sea water. Question 4 A) A student conducts an experiment in which sound waves pass through air and then through water. Which statement describes the wave speed as it passes from air to water? (1 point) Responses The speed of sound remains the same. The speed of sound remains the same. The speed of sound becomes zero. The speed of sound becomes zero. The speed of sound increases. The speed of sound increases. The speed of sound decreases. The speed of sound decreases. Question 5 A) The speed of sound in different media at increasing temperatures is shown in the data table below. The table shows the speed of sound in freshwater, seawater and air at different temperatures. Speed of Sound in Different Media at Increasing Temperatures Temperature (°C) 0 10 20 30 Speed of sound in freshwater (m/s) 1,403 1,447 1,481 1,507 Speed of sound in seawater (m/s) 1,449 1,490 1,522 1,546 Speed of sound in air (m/s) 331 337 343 355 Why does sound travel the slowest in air? (1 point) Responses The wind blocks the sound waves and carries them in all directions. The wind blocks the sound waves and carries them in all directions. The temperature of air varies more than the temperature of water. The temperature of air varies more than the temperature of water. The kinetic energy of the molecules of air is too low to transport sound waves. The kinetic energy of the molecules of air is too low to transport sound waves. The distance between molecules of air is greater than for molecules of water. The distance between molecules of air is greater than for molecules of water.

Answer 1

Here are the correct answers for each of your questions:

**Question 1**:
A) The speed of sound is generally faster in solids than in gases, because solids are denser than gases.
(However, it is important to note that while density affects sound speed, it is more related to the rigidity of the medium, which is greater in solids than in gases.)

**Question 2**:
A) They have different rigidities.

**Question 3**:
A) Sound travels faster in warmer water, both in fresh water and sea water.

**Question 4**:
A) The speed of sound increases.

**Question 5**:
A) The distance between molecules of air is greater than for molecules of water.
