each leg on the warming curve. 2.
Bellwork 2 / Warming Curve 1. Label each leg on the warming curve. 2. Describe the change in Kinetic Energy and Potential Energy as you go from Leg C to Leg D. 3. If you have a 4.89 g sample at - 11.2 C. How much energy would be required to heat the sampl e to 15.5 C?

Bell Work 3 / Specific Heat
You must first determine the specific heat of each Metal Sample. Zinc Copper Aluminum Cp= Cp= Cp=0.897 Remember, the lower the Cp the faster it will heat up and cool down. Zinc will be hottest Aluminum will be coolest

Bell Work 4 / Specific Heat
Problem 1. A piece of unknown metal with a mass 14.9 g is heated to 100.0 C and dropped into 75.0 g of water at 20.0 C. The final temperature of the system is 28.5 C. What is the specific heat of the metal

Bell Work 5 / Specific Heat
You place g of water in a coffee - cup calorimeter and the temperature of the water is 22.3°C. A 45.9 g piece of silver metal is heated to 100.0°C and added to the water in the calorimeter. The equilibrium temperature is 2 7.3 C. What is the specific heat of the metal?

1. Hw much energy will e needed to raise the temp from 88 C to 114
Bell Work 6 / q Problem 1. Hw much energy will e needed to raise the temp from 88 C to 114 C if you have a 6.92g sample of water? First, Draw the warming curve for water and include the information. II. Calculations 1. 88 to 100 (q=cp m T) energy to boil (q=mHv) to 114 (q= cp m T) Finally, add together for total energy

Bell Work 7 / Specific Heat Problem
When 80.0 grams of a certain metal at 90.0 °C was mixed with grams of water at 30.0 °C, the final equilibrium temperature of the mixture was 36.0 °C. What is the specific heat of the metal?

Bell Work 8 / Endo Exo Thermic
Is the graph an endothermic or exothermic reaction? What is the activation energy of this graph? Determine the heat of the Reaction? 4. Draw in a dotted line to represent what the graph would look like if you added a catalyst.
