1 g of ice at `0^(@)`C is added to 5 g of water at `10^(@)`C. If the latent heat is 80 cal/g, the final temperature of the mixture is

A

`5^(@)` C

B

`0^(@)`C

C

`-5^(@)`C

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`Q_1 = 5 xx 1 xx 10 = 50` cal
`Q_2 = 1 xx 80 = 80` cal
`Q_1 lt Q_2` and final temperature `= 0^(@)`
