We did the lab of latent heat of fusion of ice, and I am
confused that what the 'water equivalent' represents.
I thought it is the amount (kg) of water, but it is
mccc according to this lab manual, which unit
is (J/oC).
Please answer what the water equivalent represents and the unit
of it.

A calorimeter is to be calibrated: 69.96 g of water at 44.4oC added to a calorimeter containing 65.79 g of water at 21.7oC. After stirring and waiting for the system to equilibrate, the final temperature reached 31.9oC. a. Calculate the change in heat of the warmer water in Joules. Report your answer to three significant figures. Since heat is lost, make sure the sign of your answer is negative. b. Calculate the amount of energy gained by the cold water...

In a lab experiment involving calorimetry with brass and lead samples, a perfect calorimeter with no heat loss in which any heat lost from the metal was gained by the water was assumed. If the calorimeter was not perfect and some heat was lost to the environment, would this cause your calculated specific heat capacity of a solid (c) values to be higher or lower than the actual specific heat capacity of a solid (c) values?
What will my heat gained by the calorimeter be? and total heat
gained? Also do I represent heat loss of metal as
negative?
