Here are a set of summary notes, I made a few changes and put them into a table rather than boxes to help the flow, not that anyone would know. Thanks to the teacher who produced these- sorry there was no name on them.
A bright 2 page set of summary notes for this topic. NB Please add to this “The length of the line for vaporisation should be longer than that for melting as more energy is required to change a liqued to a gas than a solid to a liquid.
A scribble from an online lesson. The last 2 comments are perfect answers for those “Explain using the kinetic model of gases….” questions.Using a simple syringe will remind you of Boyle’s Law, if you reduce the volume pressure increases. I know this as it really hurts my finger when I squeeze the gas into a smaller space or volume.just some scribbles from an online lesson. We were trying to remember which law went with which rule and this is what we came up with BOYLE’s LAW. If you had a big BOIL and you add pressure by squeezing it the volume increases as it splatters all over the place! CHARLES’ LAW, we know this guy called Charlie and when he gets red hot his face swells up (volume increases with temperature) And GAY-LUSSAC law has been incorrectly attributed to him so we can put him in a pressure cooker (picture below) and increase the temperature. The volume is fixed so we know the pressure increases as the cooker makes a big hissing sound when it’s about to blow!

Gay-Lussac is incorrectly recognized for the Pressure Law which established that the pressure of an enclosed gas is directly proportional to its temperature and which he was the first to formulate (c. 1809). He is also sometimes credited with being the first to publish convincing evidence that shows the relationship between the pressure and temperature of a fixed mass of gas kept at a constant volume.
Maybe for the deception he should be sent to Pressure Cooker!

These laws are also known variously as the Pressure Law or Amontons’s law and Dalton’s law respectively.
