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

1. Condense butane by cooling it under its boiling point of -0.4 °C.
2. Condense butane at high pressure.
