50 gram of ice at `0^(@)`C is mixed with 50 gram of water at `60^(@)C` , final temperature of mixture will be :-

A

`0^(@)C`

B

`40^(@)C`

C

`10^(@)C`

D

`15^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A
Heat liberated when 50 g of water at `60^(@)`C converts into water at `0^(@)`C
Q = ms`DeltaQ`= 50 xx 1 x 60 = 3000 cal
From this heat, mass of ice which can be melted is
`m= Q/L = 3000/80` = 37.5g
i.e, whole ice is not melted and temperature of mixture will be `0^(@)`C.
