I see that the work I showed at the first post is incorrect, it's 0.175 instead of 0.0175.
So
Q1=(0.175)(4186)(87-θ)
Q2=(0.08)(33.5e4)
Q3=(0.175+0.08)(4186)(θ-0)
Am I setting it up correctly?
I have a question about Q3, why do we add the tea with the melted ice-water? Aren't we...
Hey rl.bhat, thanks for the reply. But I still don't quite get it. If I make the final temperature as a variable, θ, then I will get θ=102.437 deg Celsius, which is hotter than the original 87 deg.
ARRGH, I am pulling my hairs out for this problem!
Homework Statement
175 cm3 of hot tea at 87°C are poured into a very thin paper cup with 80 g of crushed ice at 0°C. Calculate the final temperature of the "ice tea". (Hint: think about two processes: melting the ice into liquid and, maybe, warming the liquid.)
