The 2.2 kg block of ice from fnt 2) is removed from the ln after reaching thermal equilibrium with the ln and is placed in a very large amount of liquid h2o at 0°c, where it comes to thermal equilibrium with the liquid h2o. assume the ice and liquid water are insulated from the environment. create a particular model of this process and use it to determine the final mass of the ice. draw two separate temp. vs. energy added diagrams to you answer this question.
