At what temperature will the speed of sound be double of its value at `0^@C ` ?

Text Solution

Verified by Experts

The correct Answer is:
A, C
`T_1=273, v_2=2V_1`
`V_1=v, T_2=?`
we know that `V a/T`
`T_2/T_1=V_2^2/V_1^2`
`rarr T_2=273xx(2)^2`
`=4xx273K`
So, temperature will be `4xx273=819^@C`
So temperature will be `4xx273=819^@C`
