3. A student goes to the cafeteria to get an iced tea. He puts 3 ice cubes (approximately 20.0 mL each, Sice = insulated cup and then fills the cup with 375 mL of tea. The tea is coming from a machine at room temperature, which is 22,5°C. The student is so immersed in studying chemistry that he forgets about his drink. When he finally goes to take his first drink, he notices that the ice has just melted. At what temperature is his iced tea? Assume the density of ice is that of water. It may be helpful to plot the temperatures on the heating curve below. lH,0=333 J/g. 2.100 J/g °C) from the ice machine (at – 15.0°C) into a well- %3D

no EXPERIMENT 8 HEATS OF REACTION 3. A student goes to the cafeteria to get an iced tea. He puts 3 ice cubes (approximately 20.0 mL each, Sice = 2.100 J/g °C) from the ice machine (at – 15.0°C) into a well- insulated cup and then fills the cup with 375 mL of tea. The tea is coming from a machine at room temperature, which is 22.5°C. The student is so immersed in studying chemistry that he forgets about his drink. When he finally goes to take his first drink, he notices that the ice has just melted. At what temperature is his iced tea? Assume the density of ice is that of water.
