A ten ounce glass of tea (285 g) is at room temperature (25.0 °C). Two ice cubes with a mass of 50.0 g and a temperature of 0.0 °C are added to the tea. Would the amount of ice added be sufficient to lower the temperature of the tea to 0.0 °C? Hint: Calculate the energy to melt the ice and then calculate the energy to cool the tea. Cp tea = 4.20 J/(g °C) %3D Hfus = 6.01 KJ/mol %3D O a. No, the energy to melt the ice is larger than the energy to cool the drink. O b. Can't tell not enough information is given. O c. Yes, the energy to melt the ice is larger than the energy to cool the drink. O d. No, the ice will melt before the drink cools to 0.0 °C.
