Condensation of gases through an increase of pressure and through cooling

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.

Learning objectives

• Condensation
