Answer:
At 357°C sound travels at 1.5 times the speed at 7°C.
Explanation:
Velocity of sound in air is directly proportional to square root of absolute temperature of the medium in which it travels
V α√T
T1= 7 °C=280K
T2=?
v2/v1= 3/2 =1.5 [ given according to question ]
V2/v1= √(T2/T1)
1.5²= T2/T1
T2= 2.25 xT1
=2.25 x 280=630K
=357 °C
. So at 357°C sound travels at 1.5 times the speed at 7°C.
