HS-PS1-9
Analyze data to support the claim that the combined gas law describes the relationships among volume, pressure, and temperature for a sample of an ideal gas.
Clarification statement: Real gases may be included at conditions near STP. The relationships of the variables in the combined gas law may be described both qualitatively and quantitatively.
Assessment boundary: Assessment is limited to the relationships among the variables of the combined gas law, not the gas law names, i.e. Boyle’s Law.
Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.
Performance Level Descriptions
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.

NGSS Dimensions
Performance expectation HS-PS1-9 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Analyzing and interpreting data: Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.
- Structure and properties of matter: the concept of an ideal gas is a model to explain behavior of gases. A real gas is most like an ideal gas when the real gas is at low pressure and high temperature.
- Patterns: Mathematical representations can be used to identify certain patterns.
