If on heating a liquid through 80^(0)C, ...

If on heating a liquid through `80^(0)C`, the mass explled is `(1)/(100)`th of mass still remaining, the coefficient of apparent expansion of the liquid is

A

`1.25 xx 10^(-4)//""^@C`

B

`12.5 xx 10^(-4)//""^(@)C`

C

`1.25 xx 10^(-5)//""^(@)C`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`gamma_(app) = ("Mass expelled")/("Mass remained " xx Delta T) = (x//100)/(x xx 80 ) = (1)/(8000)`
`= 1.25 xx 10^(-4) // ""^(@)C`.
