1. A 500 g piece of iron (Fe) changes 7°C when heat is added. How much heat energy produced this change in temperature?
2. When 300 J of energy is lost from a 125 g object, the temperature decreases from 45°C to 40°C. What is the specific heat of this object?
3. 1200 J of heat energy is added to a liquid with a specific heat of 0.57 J/g°C. If the temperature increases from 20°C to 33°C, what is the mass of the liquid?
4. If 50.0 grams of aluminum (Al) at 97°C is heated to 107°C, how many Joules are involved? 5. If 100 grams of metal at 100°C is cooled to 31.3°C, and heat given off is 2611 J, what is the specific heat of the metal? What metal is it?
PLEASE HELP NO BOTS OR I AM REPORTING!!
