You drop an ice cube into an insulated bottle full of water and wait for the ice cube to completely melt. the ice cube initially has a mass of 80.0 g and a temperature of 0°c. the water (before the ice cube is added) has a mass of 860 g and an initial temperature of 26.0°c. what is the final temperature (in °c) of the mixture? (assume no energy is lost to the walls of the bottle, or to the environment.)
