Question
1. What is the specific heat in J/g°C for a metal sample with a mass of 78.9 g which absorbs 753 J of energy when its temperature increases from 25.0°C to 99.0°C? What is the identity of the metal? 2. Equal masses of water at 20°C and iron at 40°C are put together in a foam cup. The water has a specific heat of 1 cal/g °C and the iron has a specific heat of 0.113 cal/g °C. What do you think the final temperature will be of both the water and the iron in the foam cup? Show your work.
