Temperature and Sound Speed

What is the relationship between temperature and the speed of sound?

• The speed of sound is constant regardless of temperature changes.

• The speed of sound decreases with an increase in temperature.

• The speed of sound increases with an increase in temperature.

• Temperature has no effect on the speed of sound.

How does the speed of sound change with increasing temperature?

• The speed of sound decreases with increasing temperature.

• The speed of sound remains constant regardless of temperature.

• The speed of sound is unaffected by changes in temperature.

• The speed of sound increases with increasing temperature.

At what temperature does sound travel fastest in air?

• At 20 degrees Celsius (68 degrees Fahrenheit), sound travels at approximately 343 meters per second, but it continues to increase with higher temperatures.

• At -10 degrees Celsius (14 degrees Fahrenheit), sound travels faster than at 20 degrees Celsius.

• At 100 degrees Celsius (212 degrees Fahrenheit), sound travels at 300 meters per second.

• At 0 degrees Celsius (32 degrees Fahrenheit), sound travels at its fastest.

What is the speed of sound in air at 20 degrees Celsius?

• 343 m/s

• 250 m/s

• 300 m/s

• 400 m/s

How does humidity affect the speed of sound?

• Humidity has no effect on the speed of sound.

• Humidity only affects the speed of light.

• Humidity decreases the speed of sound.

• Humidity increases the speed of sound.

Why does sound travel faster in warmer air compared to cooler air?

• Sound travels faster in warmer air because of increased humidity.

• Sound speed is unaffected by temperature changes in air.

• Sound travels faster in cooler air due to less molecular motion.

• Sound travels faster in warmer air due to increased molecular motion.

What is the effect of temperature on the speed of sound in water?

• The speed of sound in water increases with temperature.

• The speed of sound in water decreases with temperature.

• Temperature has no effect on the speed of sound in water.

• The speed of sound in water is constant regardless of temperature.

How does the speed of sound in solids compare to that in gases at the same temperature?

• The speed of sound in gases is faster than in solids at lower temperatures.

• The speed of sound in solids is faster than in gases at the same temperature.

• The speed of sound in solids is the same as in gases at the same temperature.

• The speed of sound in solids is slower than in gases at the same temperature.

What is the formula to calculate the speed of sound in air based on temperature?

• v = 331 + (0.7 * T)

• v = 300 + (0.5 * T)

• v = 340 + (0.4 * T)

• v = 331.3 + (0.6 * T)

How does altitude affect the speed of sound in the atmosphere?

• Higher altitudes increase the speed of sound due to less air density.

• Altitude has no effect on the speed of sound.

• The speed of sound is constant regardless of altitude.

• Altitude affects the speed of sound by decreasing it due to lower temperatures at higher elevations.
