### Question on 8.21

**Mon Jan 08, 2018 9:16 pm**Here's Question 8.21:

A piece of copper of mass 20.0 g at 100.0 degrees Celsius is placed in a

vessel of negligible heat capacity but containing 50.7 g of water

at 22.0 degrees Celsius. Calculate the final temperature of the water. Assume

that no energy is lost to the surroundings.

I understand how the solution manual solves it. However, I was wondering if there is an easier method to solve this type of question instead of using equations that might take longer. Please let me know when possible. Thank you.
