Gay-Lussac's Law: pressure and temperature from a real gas run

Students use the UNED Gay-Lussac remote lab to test whether pressure is approximately proportional to absolute temperature at fixed volume.

• Use a real remote Gay-Lussac lab observation to collect pressure-temperature evidence.
• Convert Celsius temperatures to kelvin before using a gas-law ratio.

Includes student questions and response prompts.

Gay-Lussac: does pressure rise when gas is heated?

Observe a real Gay-Lussac run and use a few data rows to decide how pressure changes when a fixed-volume gas is heated.

• Observe the Gay-Lussac remote run and describe how pressure and temperature change together.
• Use 4 real data rows to support a qualitative claim.

Gay-Lussac: graphing pressure and temperature

Use real Gay-Lussac data to build a pressure versus absolute temperature graph and interpret the pattern.

• Prepare a graph of pressure versus temperature in kelvin.
• Use real rows spread across the run to interpret an approximately linear pattern.

Gay-Lussac: how far the model goes

Compare measured data, a linear fit, and an extrapolation to decide what each one can support.

• Interpret a linear model inside the measured range without overstating an extrapolation.
• Explain why one real run does not exactly prove absolute zero.

Gay-Lussac: why Kelvin matters

Observe a real run and compare what happens when P/T uses temperature in Celsius and in kelvin.

• Convert Celsius temperatures to kelvin in real lab data.
• Calculate and compare several P/T(K) values.

Includes student questions and response prompts.
