and 5 g of ice at
are mixed together in a calorimeter. What is the final temperature of the mixture? (Take, specific heat of ice
and latent heat of fusion of ice
)

Here, specific heat of ice, 
Specific heat of water,
Latent heat of fusion of ice,
Here, ice will absorb heat while hot water will release it.
Let T be the final temperature of the mixture.
Assuming water equivalent of calorimeter to be neglected.
Heat given by water, 

… (i)
Heat absorbed by ice,

= 
=
… (ii)
According to principle of calorimetry,
