Principle
Gases are condensing when they are cooled and at high pressure. In this experiment butane is condensed by cooling it to ca. -15 °C. In the second part of the experiment butane is condensed by compressing it.
Benefits
- Compact setup
- Perfect as demonstration and student experiment
- Beautiful illustration of the phase transition from gaseous to liquid
Tasks
- Condense butane by cooling it under its boiling point of -0.4 °C.
- Condense butane at high pressure.
Learning objectives
