The density of ice is x g `cm^(-3)` and that of water is y g `cm^(-3)`. What is the change in volume when m gram of ice melts ?

A

`m ( y-x) c.c`.

B

`(y-x)/m c.c.`

C

`m xy (x-y) c.c`.

D

`m(1/y-1/x)c.c.`

Text Solution

Verified by Experts

The correct Answer is:
D
Vol. of m gram of ice =`m/x`c.c
Vol. of m gram water formed`=m/yc.c`
Change in vol. on melting =`(m/y-m/x)`
`=m(1/y-1/x)`c.c.
Correct choice is (d).
