On a hot summer day, you decide to make some iced tea. First, you brew 1.50 LL of hot tea and leave it to steep until it has reached a temperature of TteaTteaT_tea = 75.0 ∘C∘C. You then add 0.975 kgkg of ice taken from the freezer at a temperature of TiceTiceT_ice = 0 ∘C∘C. By the time the mix reaches equilibrium, all of the ice has melted. What is the final temperature TfTfT_f of the mixture?
