Simple Question! How to calculate heat absorbed by ice or water?
So, I am trying to understand how would you approach the equation, Qin = Qout to find the heat, temperature or anything else. (The equation with M,S,L,T)
If the problem says that "ice" is abosorbed, will that has to go in the first part and water in the second part? Can you please elaborate this process to me?

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.

How much heat is required to change 50 g of ice at 0 oC into liquid water at 0 oC? Qmelt ice = cal 2) If 300 g of water initially at 25 oC released the amount of heat that you found in Part (1), what would its temperature be afterward? Tafter = oC 3)If you were to combine 50 g of liquid water at 0 oC with 300 g of the water at the temperature you found in Part...

8.12 water enters a tube at 27 0 with a llow rate of 450 kg/h. The heat transfer from the tube wall to the fluid is given as q(W/m)-ax, where the coefficient a is 20 W/m2 and x (m) is the axial distance from the tube entrance (a) Beginning with a properly defined differential con trol volume in the tube, derive an...

A) How much heat must be absorbed by a 23.0 g sample of water to raise its temperature from 30.0 ∘C to 50.0 ∘C? (For water, Cs=4.18J/g∘C.) Express your answer to three significant figures and include the appropriate units. ΔErxn = nothing kJ/mol B) anganese reacts with hydrochloric acid to produce manganese(II) chloride and hydrogen gas. Mn(s)+2HCl(aq) → MnCl2(aq)+H2(g) You may want to reference (Page 271) Section 6.7 while completing this problem. Part A When 0.635 g Mn is combined...
