Question
I attached the solution and the answer
Only do part C please, it is NOT connected to parts A and B.
I do not understand in the given solution how they are getting those temperatures and the formula I’ve never seen it before, how is m(w) c(ice) in the same equation I think it’s simplified, please explain

Problem 4-Fluids and Heat
(a) An object, when is submerged in gasoline (specific density = 0.68) has an apparent weight w'= 0.92 kg, while is actual weight is w= 1.0 kg. What is the
object made of?
(b) Gasoline is pumped along a vertical pipe with constant cross-sectional area. If the gasoline pressure at the bottom of the pipe is 3 atm, what will be the
pressure 20 m above?
(c) Suppose that you mix two liters of water, with initial temperature Tw= 10 °C, with an unknown, initial mass of ice, mice, and initial temperature Tice= -40
°C. In the final state, you find 100% ice with final temperature Tfin -10 °C. Evaluate the initial ice mass.
Transcribed Image Text:(c) We can use the formula
mw Cw (OT) w + MN Lw + MwCice (ST)₁ = Micelice (ST)
where
Cice =
mw = 2kg; cw = 1 kcal/kg°C,
0.5 kcal/kg°C, Lw = 80 kcal/kg, (AT) w = 10°C,
(AT), = 10°C, (01)₂ = 30 °C. Solving for mice:
