Features over 30 inquiry based labs covering the core topic areas of mechanics, electricity and magnetism, optics, thermodynamics and more.
Heat of vaporization
Use a temperature sensor to develop a better understanding of the phase change from gas to liquid.
This experiment enhances students' understanding of energy transfer in the form of heat, allowing them to:
- Develop a better understanding of the phase change from gas to liquid.
- Use a graph of temperature verses time to understand the connection between heat energy transfer and phase change.
- Determine the latent heat of vaporization of water.
Students gain experience using the following procedures:
- Assembling an apparatus to isolate and measure the temperature change that results from condensing water vapor into liquid water.
- Analyzing a graph of temperature versus time to determine a change in temperature.
- Calculating the heat of vaporization of water based on energy transfer in the form of heat.
