Several interesting experiments of state or phase changes. Sublimation, deposition (reverse sublimation), condensation and vaporization (boiling) of carbon dioxide or CO2. This chemical compound cannot be found in a liquid state at atmospheric pressure. To do this, it needs to be above 5.1 atmospheres of pressure.
We are going to convert butane from a gaseous state to a liquid (condensation or liquefaction) by increasing pressure and also by cooling. We will also see that butane in a liquid state boils at 1 ºC.
Using a syringe we will lower the pressure of the acetone to observe how it boils and turns into vapor, that is, it goes into the gas phase and vice versa, it condenses as the pressure increases.
We will do the same with hot water in a syringe.
