An iron ball of mass 0.2 kg is heated to...

An iron ball of mass 0.2 kg is heated to `10^(@)C` and put into a block of ice at `0^(@)C`. 25 g of ice melts. If the latent heat of fusion of ice is `80 cal g^(-1)`, then the specific heat of iron in `cal g^(-1^(@))C` is

A

1

B

0.1

C

0.8

D

0.008

Text Solution

Verified by Experts

The correct Answer is:
B
Heat taken = heat given
or `mcDeltatheta = mL`
`therefore(200)(s) (100)=25 xx 80`
`therefore`c= 0.1 cal//g^(@)`C
