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.
