This is my 1 minute video of the experiment (Alex). I meant to say in this video that pressure goes up, not down. Gases will exert a pressure.

This is my individual video where I explain the Graph corresponding to the Experiment number 6: Vapour pressure of Alcohols

Video of an explanation of the experiment and how Ethanol compares to other alcohols:

Observations on Experiment 6: Vapour Pressure of Alcohols

Experiment 6: Vapour pressure in alcohols

OBSERVATIONS
- Vacuum lines exerted vapour pressures.
- Different alcohols have different vapour pressure.
- Different alcohols have different amounts of carbon atoms which affects its vapour pressure.
- The molecules we studied adopt different shapes.
- Alcohols are composed of three elements: Carbon (C), Oxygen (O and Hydrogen (H).
- The larger the molecule was, the lower the vapour pressure was.
- We can obtain graphs from the data we obtain with either the vapour pressure versus the molecular weight or the number of carbon atoms.
- Alcohols can be represented by:

Ethanol and its different figures

These were the photographs taken from different points of view, of the structure of an Ethanol molecule.

That day we experimented with the pressures that we could apply on ethanol.
