Discipline - Chemistry

Core Idea - Energy

[HS.CHEM.3.4] - Provide evidence from informational text or available data to illustrate that the transfer of energy during a chemical reaction in a closed system involves changes in energy dispersal (enthalpy change) and heat content (entropy change) while assuming the overall energy in the system is conserved. State Assessment Boundary: Calculations involving Gibbs free energy are not expected in state assessment.

Predecessor Standards:

  • 6.NS.C.5
    Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, and positive/negative electric charge). Use positive and negative numbers (whole numbers, fractions, and decimals) to represent quantities in real-world contexts, explaining the meaning of zero in each situation.
  • 7.PS.3.4
    Conduct an investigation to determine the relationships among the energy transferred, how well the type of matter retains or radiates heat, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample. State Assessment Boundary: Calculations of specific heat or the total amount of thermal energy transferred are not expected in state assessment.

Successor Standards:

No Successor Standards found.

Same Level Standards:

  • WCA.9-10.9
    Draw evidence from informational texts to support analysis, interpretation, reflection, and research. (See grades 9-10 Reading Standard 1 for more on the use of textual evidence.)
  • HS.CHEM.1.4
    Develop a model to illustrate the energy transferred during an exothermic or endothermic chemical reaction based on the bond energy difference between bonds broken (absorption of energy) and bonds formed (release of energy). Clarification Statement: Examples of models may include molecular-level drawings and diagrams of reactions or graphs showing the relative energies of reactants and products. State Assessment Boundary: Calculations using Hess’s law are not expected in state assessment.
  • HS.PHY.3.1
    Use algebraic expressions and the principle of energy conservation to calculate the change in energy of one component of a system when the change in energy of the other component(s) of the system, as well as the total energy of the system including any energy entering or leaving the system, is known. Identify any transformations from one form of energy to another, including thermal, kinetic, gravitational, magnetic, or electrical energy, in the system. Clarification Statement: Systems should be limited to two or three components and to thermal energy; kinetic energy; or the energies in gravitational, magnetic, or electric fields.
