11. Calculate the amount of heat transferred when 550 grams of water cools from an initial temperature of
25.0 °C to a final temperature of 4.0 °C. The specific heat capacity of liquid water is 4.184J/g °C. Please
express you answer as a number in units of k), and be careful about the sign (positive or negative number?)
since that shows the direction of heat flow.
