3. You see a gold ring in a flea market that you'd like to have, and the price seems right, so you buy it. On the drive home you wonder if it's really gold. You do a quick experiment and find it takes 38.7 J of heat to raise the temperature of the 6.00 g ring from 25°C to 75°C. You know that the specific heat of gold is 0.128 J/g°C; is your ring really made of gold?

A common problem is to mix two liquids, say 125g of water at 24°C with the same mass of water at 48°C. The
water is mixed in an insulated container that prevents energy from entering or leaving. What is the final temperature of
the system?
