Question

at what temparature the velocity of sound in air be 1% more than the velocity of sound at 27°C in air?​

Answer 1

Answer:

Correct option is

B

927

o

C

Speed of sound in air is given as

M

0

3RT

Thus the speed V∝

T

Thus is velocity becomes double, the temperature must go to four times its initial value.

Initial temperature=27+273=300K

Hence final temparature=1200K=927

∘

C
