The density of ice is xgm//c c and that ...

The density of ice is `xgm//c c` and that of water is `y gm//c c`. What is the change in volume in `c c`, when `m gm` of ice metls?

A

`m(y-x)`

B

`(y-x)//m`

C

`mxy(x-y)`

D

`m(-1//y +1 //x)`

Text Solution

Verified by Experts

m = volume `xx` density
Mass remains constant
` V_(ice) xx rho_(ice ) = V_(water ) xx rho_(water)`
`V_(water) = (V_(ice) xx rho_(ice))/( rho _(water)) = m/y `
`DeltaV = - V_(water) +V_(ice) = m (-1/y +1/x)`
