###### Question:

1. A 2.80 g lead weight, initially at 11.0 ∘C, is submerged in 8.19 g of water at 53.0 ∘C in an insulated container.

What is the final temperature of both the weight and the water at thermal equilibrium?

2. It takes 45.0 J to raise the temperature of an 9.60 g piece of unknown metal from 13.0∘C to 24.6 ∘C. What is the specific heat for the metal?

3. The molar heat capacity of silver is 25.35 J/mol. ∘C. How much energy would it take to raise the temperature of 9.60 g of silver by 17.1 ∘C?

4. What is the specific heat of silver?
