EXPERIMENTS WITH VERNIER GAS PRESSURE SENSOR, STAINLESS STEEL TEMPERATURE
DescriptionExp-1 Ideal gas law (Five Experiments).
Exp-2 Heat engines (Six Experiments).
IDEAL GAS LAW
Objectives:
- Collect pressure vs. volume, pressure vs. number, and pressure vs. temperature data for a sample of air in an enclosed container.
- Determine relationships between these pairs of variables.
- Determine a single expression relating these variables.
- Determine the constant of proportionality for the relationship between pressure, volume, and temperature.
- Use kinetic molecular theory (KMT) to model the behavior of the gas at various points on each graph.
HEAT ENGINES
Objectives:
- Design and create a thermodynamic system consisting of a flask, tubing, syringe, and pressure sensor.
- Relate the terms isothermal, isochoric, isobaric and adiabatic to various thermodynamic processes, and how to move your thermodynamic system through these processes.
- Collect pressure, volume and temperature data for three of these processes.
- Analyze the various P-V processes to keep track of the work (W) done by or on the enclosed gas and the heat (Q) transferred between the gas and the surroundings.
- Use the first law of thermodynamics to account for the change in internal energy in each of these processes.
- Determine the total work done by enclosed gas in various thermodynamic cyclic processes.
