2. 1.000 L of boiling water is added to 3.000 L of water at 25.00 degrees Celsius. What will be the final temperature? (Hint, write expressions for heat gained by each with Tf as a variable, and solve for Tf) (( double hit: loosing heat is the same thing as gaining a negative amount of heat.))

3. How many grams of propane would you have to burn to get the water to the boing point in in Example 1?

Example 1 is: 0.800 g of propane (C3H8) is burned in a flame. All the heat released is absorbed by a bucket containing 3.500 kg of water. The temperature of water increases by 2.531 degrees Celsius.
