On a hot summer day, you decide to make some iced tea. First, you brew 1.50 L of hot tea and leave it to steep until it has reached a temperature of T_Tea = 75.0 ∘C . You then add 0.975 kg of ice taken from the freezer at a temperature of Tice = 0 ∘C . By the time the mix reaches equilibrium, all of the ice has melted. What is the final temperature Tf of the mixture? For the purposes of this problem, assume that the tea has the same thermodynamic properties as plain water. The specific heat of water is c = 4190 J/kg⋅∘C . The heat of fusion of ice is Lf = 3.33×105 J/kg . The density of the tea is ρtea = 1.00 kg/L
