Lesson 4 Effects Of Temperature To The Speed Of Sound

Question 1

Anything that we can hear from our surroundings, things that we can hear and travels in the form of sound waves and the vibrations are hurt when they reach our ears.

Answer 1

Sound

Question 2

Sound waves are affected by many factors as they travel in various channels and media. Which media will the sound be the fastest to travel.
A.Solid
B.Liquid
C.Gas
D.Plasma

Answer 2

A

Question 3

In which matter does the sound waves travels the slowest

Answer 3

Gas

Question 4

It is the ability of a deformed material to return to its original form, shape or size after removing the force that causes the deformation.

Answer 4

Elasticity

Question 5

It is the intrinsic property of any object. It is an object’s mass per unit volume which is obtained by dividing the mass of the object by its volume. It is a description of how compact the atoms and molecules in an object.

Answer 5

Density

Question 6

Speed of sound is measured in 0°C=331m/s every increase of Celsius is
1°C increase= 0.60 m/s increase. Measure the speed of sound if the air temperature is 30°C

Answer 6

349m/s

Question 7

What temperature does the sound travel the fastest.

Answer 7

Warmer; the warmer the temperature the faster the sound travels

Question 8

Describe as the turning back of the wave as it hits a barrier.Its example is echo

Answer 8

Reflection

Question 9

Multiple reflections or echoes in a certain place. This best fits the bathroom which enhances the voice.

Answer 9

Reverberation

Question 10

The change of sound waves as they pass from one medium to another.

Answer 10

Refraction

Question 11

What are the factors of speed of sound

Answer 11

Density elasticity and temperature

Question 12

When does an echo occurs

Answer 12

When a sound wave is a reflected

Question 13

What phenomenon explains why sound is heard at longer distance at night than in day

Answer 13

Refraction
