Heat and Thermodynamics
The Study of Heat Flow and Heat Exchanges
Course Objectives•Differentiate between exothermic and endothermic reactions
•Use kinetic theory to define heat transfer
•Use Calorimetry to determine heat transfer
•Solve problems in heat flow and temperature change
Student Activities
• Pretest• Lab work and
report• Unit test
• Warm-up Questions
• Demonstrations and questions
• Reading and questions
• Worksheet
Identify the reaction(Warm Up)• Does this reaction
absorb heat?• Does this reaction
release heat?• Is this an
exothermic or endothermic reaction?
Heat Equations
Two Basic Heat Equations:
(delta)H=m X Cp X (delta)T
(delta)H=m X Heat of reaction
