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.

NGSS Dimensions

Performance expectation HS-PS1-9 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices

• 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.

Disciplinary Core Ideas

• 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.

Crosscutting Concepts

• Patterns: Mathematical representations can be used to identify certain patterns.
