Question
It was stated here that the T2 they got is 19.14 but when I tried to solve it myself, I got 20.38. Can someone explain how did they get the value?
Theoretical Final Temperature: Qlost+Qgained =0 = -Qwater Quilver Q = mcAT (50g)(0.235 J/g °C)(T₂ - 80°C) = -(200g)(4.184 J/g °C)(T₂-20°C) T₂ = 19.14550633295
