La velocidad del sonido

The video tutorial explains that the speed of sound varies under different conditions, such as temperature and the medium through which it travels. Sound moves faster in water than in air and even faster in solids due to stronger particle interactions. The speed of sound also increases with temperature as molecules move faster. In less dense media, sound travels quicker because lighter molecules require less energy to move. Helium, being lighter than air, significantly increases sound speed. Overall, the speed of sound is influenced by several factors, making it impossible to define a single speed.

Under what conditions does sound travel faster in water than in air?

• When the air is colder

• When the water is warmer

• Under all conditions

• When sound travels through a vacuum

How does temperature affect the speed of sound?

• Higher temperatures increase sound speed

• Higher temperatures slow down sound

• Lower temperatures increase sound speed

• Temperature has no effect on sound speed

What role does elasticity play in the speed of sound?

• Elasticity decreases sound speed

• Elasticity has no effect on sound speed

• Higher elasticity increases sound speed

• Lower elasticity increases sound speed

In which type of medium does sound travel the fastest?

• Liquids

• Gases

• Solids

• Vacuum

Why does sound travel faster in helium compared to air?

• Helium molecules are heavier

• Helium is denser than air

• Helium requires less energy to move

• Helium is a solid
