Plant Oils, Biofuels And Nanoparticles Flashcards
What plants can we extract oils from?
Sunflowers Olive Rape seed Lavender Almond Pine nut
How does the pressing method work?
Put the seeds into a mortar then crush them with a pestle
How does distillation work?
Put the plant in the water then you boil it, the water and oil evaporate, the condenser cools down the steam that came from the oil. Then it drips out into a container. All the water and impurities are removed.
Name some biofuels
Hydrogen
Biogas - cow poo
Biodiesel - vegetable oil
Ethanol, propanol = bioacohol

What do nanoparticles do for the sunset?
Give it the red colouring
How do nanoparticles help birds?
Help them navigate
Why do things behave differently at nanoscale?
Because they have a bigger surface area
