1 Specific Heat Capacity Lab Do Now: Look at the set-up picture below, make a prediction about what do you think will happen when the two containers of water is mixed. (Note: Assuming no heat lost to the environment!) Warm Water: m = 50g of warm water T i = 90 C Cold Water: m = 50g of cold water T i = 10 C Prediction: Answer the following questions: 1: Which direction is heat transfer happening? 2. Why are the Styrofoam cups necessary?
2 Demonstration: Temperature Change of Warm Water T f = T i = Heat Lost by the Warm Water Knowns: (Place a? in the unknown appropriate quantity) Q = m = 50 g c sp = Temperature Change of Cold Water Knowns: (Place a? in the unknown appropriate quantity) Q = m = 50 g T f = T i = Heat Gained by the Cold Water c sp =

4 Go to: Silver and Water: Set Up the Experiment (make sure your screen matches the following) Run the experiment by clicking Heat gained by the water: (watch out for the now!) Knowns: (Place a? in the unknown c = J/(g-K) Heat lost by the silver: Knowns: (Place a? in the unknown c = Compare the heat lost by the silver to the heat gained by the water The heat lost by the silver is ( LARGER THAN, AROUND THE SAME SIZE AS, SMALLER THAN ) the heat gained by the water.
5 Copper and Water: Set Up the Experiment (make sure your screen matches the following) Run the experiment by clicking Heat gained by the water: (watch out for the again!) Heat lost by the copper: c = J/(g-K) c = J/(g-K) Compare the heat lost by the copper to the heat gained by the water The heat lost by the copper is ( LARGER THAN, AROUND THE SAME SIZE AS, SMALLER THAN ) the heat gained by the water.
6 Determine the Specific Heat of Metal X : Set Up the Experiment (make sure your screen matches the following) Run the experiment by clicking Heat gained by the water: (watch out for the again!) Specific Heat Capacity of Metal X : c = c = The heat lost by Metal X will have the same magnitude as the heat gained by the water. A - sign is used to indicate loss of energy Heat energy lost by Metal X : _ J
7 Determine the Specific Heat of Metal Y : Set Up the Experiment (make sure your screen matches the following) Run the experiment by clicking Heat gained by the water: (watch out for the now!) Specific Heat Capacity of Metal Y : c = c = The heat lost by Metal Y will have the same magnitude as the heat gained by the water. A - sign is used to indicate loss of energy Heat energy lost by Metal Y : _ J
8 CER Conclusion: Question: How does the amount of matter (its mass) affect its change in temperature? Claim: Write a statement that answers the question. Evidence: Provide sufficient and appropriate data to support your claim. Reasoning: Explain how the data supports your claim. Make sure you include scientific explanation
Heat can be thought of as the flow of energy between two bodies because of a difference in temperature
Why? The amount of heat energy released or absorbed by a chemical or physical change can be measured using an instrument called a calorimeter. This measurement is based on the law of energy conservation.
