A.J. is drinking 500 mL (or 0.50 kg) of Dr. Pepper at 20 C. He then adds 100g of ice from the -20 C freezer to cool off to enjoy it more while studying for his exam. (cice = 2.1 x 10^3 J/kgK) Draw a T vs Q graph of the situation. Hint: think of the critical point. What is the final temperature of the ice-soda mixture? If the temperature is 0 C, how much of the ice was melted? Assume that you have a well-insulated cup and that soda can be treated as water. Explain your reasoning.
