In this unit, the focus will be on the qualitative and quantitative role of energy in chemical and physical change.
Enduring Understandings
The students will understand that:
- heat is conserved in a chemical system and its surroundings and can be calculated appropriately.
- different materials are influenced by heat differently.
- energy can be transferred from one form to another.
- energy is a product or a reactant in all chemical changes.
- there is a relationship between heat and temperature.
Essential Questions
- How is heat conserved in a chemical system and its surroundings?
- Given the same mass, why do different materials heat at different rates?
- What are the different forms of energy and how are they related?
- How is energy related to chemical change?
- What is the relationship between heat and temperature?
Essential Skills
The students will be able to:
- recognize and calculate heat quantities.
- write thermochemical equations, calculate heat quantities and relate them to changes in matter.
