It includes nicotine. 4The user inhales the nicotine – just as in smoking. Review ConsiderEngage Aerosol A mixture of tiny liquid droplets and/or pieces of solid mixed with a gas.

Student sheets SS1 Particles and vaping Moving around in the air The aerosol Solvent: propane-1,2,3-triol Solutes: nicotine and water The aerosol is tiny droplets of liquid water, liquid propane-1,2,3-triol, and liquid nicotine mixed with the air. The air is mainly nitrogen and oxygen. The exhaled breath of an e-cigarette user includes nicotine vapour. The nicotine particles mix with the air. The air is mainly nitrogen and oxygen. Nitrogen and oxygen particles are smaller and lighter than nicotine particles. In the gas state, particles move randomly. They collide with each other frequently which makes them change direction. The nicotine vapour spreads out from a place where there are many nicotine particles to a place where there are fewer. In other words, they move from an area of high concentration to an area of low concentration. This is diffusion. The solution In the solution solvent particles surround solute particles. There are more solvent particles than solute particles.

  39. 39. Student sheets SS2 Risks and benefits of a ban on indoor vaping in public places A B C D E F If people have to go outside to vape, they might as well smoke cigarettes instead. So it is possible that more people will get lung cancer. Since nicotine damages foetal brains, fewer babies will be born with brain damage. People might vape more at home. So children might be exposed to more nicotine. Lung cancer risk of smoking reported by the NHS Foetal brain damage reported in paper in the journal Nature A ban might make people think that the risks of smoking and vaping are the same. This makes smokers less likely to use e-cigarettes to help them quit smoking. Association of e-cigarette manufacturers The concentration of nicotine in the blood of passive vapers is similar to that of passive smokers. Reported by the World Health Organisation Exhaled nicotine remains on surfaces for many months. Other people can absorb this nicotine through their skin.
