## What is the speed of sound in the air if the temperature is 30 C?

Temperature of air ϑ in °C Speed of sound c in m/s Time per 1 m Δ t in ms/m
+40 354.94 2.817
+35 351.96 2.840
+30 349.08 2.864
+25 346.18 2.888

## At what temperature will the velocity of sound in air be double the velocity of sound in air at 0 C?

So, the answer is, at 1092K or 819∘C, the speed of sound will be double the value of its speed at STP.

## At what temperature velocity of sound in air is 1.5 times the velocity at 7 C?

Velocity of sound in air is dependent on the absolute temperature of the medium in which it travels. It is proportional to square root of T. T2 = ? So at 357°C sound travels at 1.5 times the speed at 7°C.

## At what temperature the velocity of sound in a gas is thrice of its velocity at 0 C?

# Solution – Hence, speed of sound will triple at 2184 ℃.

819 Celsius

27∘C

## At what temperature does sound velocity at 27 C doubles?

Here n is the number density. kb Boltzmann constant and T1 and T2 are temperatures. T2= 1200 degrees = 1200-273 = 927 degrees.

340 m/s

## When a tuning fork produces sound waves in the air?

Frequency of a wave is characterised by the source of the wave , which produces disturbance , therefore it doesn’t change when medium is changed . So it doesn’t matter whether sound is in air or material of tuning fork , frequency will not change .

## At what temperature the velocity of sound becomes double than that of at 10 C?

Absolute temperature is equal to degree Celsius plus 273. Temperature in degrees Celsius = 1132 – 273 = 859 degree Celsius. At 859 degree Celsius or at 1132 Kelvin temperature velocity will be double the velocity at 10 degree Celsius.

## Where is the velocity of sound maximum?

Sound moves quickly in solids as compared to air, fluid or vacuum. Sound moves at a higher rate via denser media. The density of the solid is greater than the densities of air, liquid & vacuum. Sound velocity in the medium of Vacuum < medium of gas < medium of liquid < medium solid.

332 m/s.

## When temperature increases the frequency of a tuning fork?

Frequency of tuning fork decreases with increase in temperature.

## At what temperature will the speed of sound in air be 1.75 times its speed at NTP?

5) At what temperature will the speed of sound in air be 1.75 times its speed at N.T.P? [Ans: 836 k = 563 °C] 1:45.

204∘ K.

## When the temperature of an ideal gas is increased by 600k?

When the temperature of an ideal gas is increased by 600 K , the velocity of sound in the gas becomes √3 times the initial velocity in it. The initial temperature of the gas is. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

## What is the speed of the sound in air of 250 C temperatures Brainly?
