Unit 8: Heat

SC.912.P.10.4 - Describe heat as the energy transferred by convection, conduction, and radiation, and explain the connection of heat to change in temperature or states of matter. 

• describe heat as a transfer of energy

• differentiate between heat and temperature

• define and differentiate among convection, conduction, and radiation

• explore the relationship between heat and changes in temperature or states of matter

SC.912.P.10.5 - Relate temperature to the average molecular kinetic energy. 

• describe temperature change as a change in molecular velocities

• quantitatively explore the relationship between temperature and the average molecular kinetic energy (KE)

• use the kinetic theory of gases to qualitatively describe the relationship between temperature and pressure

SC.912.P.10.7 - Distinguish between endothermic and exothermic chemical processes. 

• justify a chemical process as either endothermic or exothermic from a potential energy diagram

• relate endothermic and exothermic to enthalpy

• identify and differentiate a chemical reaction/process as endothermic and exothermic through empirical evidence and thermochemical equations

• use the potential energy diagram to classify chemical reactions as endothermic and exothermic

• conceptually relate enthalpy to endothermic and exothermic reactions through thermochemical equations and potential energy diagrams.

SC.912.P.10.8 - Explain entropy's role in determining the efficiency of processes that convert energy to work. (Content Complexity Level 3)

• recognize that there is a natural tendency for systems to move in a direction of disorder or randomness (entropy)

• describe entropy as a quantity that measures the order or disorder of a system and that this quantity is larger for a more disordered system

• describe the relationship between energy and work

SC.912.P.10.7

• How are endothermic reactions and exothermic reactions similar?

• How are endothermic reactions and exothermic reactions different?

SC.912.P.10.8

• When energy is added to a system, what happens to the rate of the reaction?

• Does an increase in entropy have an effect on the chemical reaction?

• What happens to the motion of the particles as the temperature increases?

• If a substance changes state from liquid to a gas, how is entropy impacted?
