Question

Hot water is mixed with an amount of ice having an equal mass to that of the water
and an initial temperature of 0 °C. What should the initial temperature of the hot water be to
achieve a final water temperature of 5 °C with all the ice melted? The specific heat capacity of
water is 4.2 kJ/(kg K) and the specific latent heat of fusion for ice is 334 kJ/kg. Assume that no
heat is lost to the surroundings.

Answer 1

:)
I forgot the formulas

Answer 2

formula.... M*C(INITIAL TEMPERATURE-FINALTEMP)=M *C (FINALTEMP - INITIAL TEMP)
where m=mass
c=specific heat capacity
and
t=temperature

Answer 3

ok, thanks
