I have to work these problems:
1. Find the final temp. of 709.2 joules of energy is added to 29.2g of water at 38.3C (degrees Celsius).
2. 2700 joules is absorbed by 146g of water at 22.9C. What is the final temp. of water?
3. A 30.0g samples of an unknown metal at 86.0C is added to 25.2g of water at 14.6C. The final temp. of the system is 22.0C. What is the specific heat?
Please explain to me how to work these problems, thank you so much , i really appreciate it.
