Academics

We have 651 g of lead which we have cooled down in the freezer to -5.28 degrees C. We also have a jar containing 1000 g of water at room temperature, which is 21.32 degrees C. If we drop the lead into the water, find the final temperature (degrees C) of the water when the lead and water have come to a common temperature. Neglect any flow of heat to or from the environment. Give the answer to 4 significant figures.
