Evaporation will happen faster if..
-the temperature is higher -there is more surface area from which particles can escape -air is moving over the surface of the liquid

What is kinetic theory?
kinetic theory is an idea or model which enables us to have a clearer understanding of the behaviour of matter in different situations.
7 of 12
Explain particles in a solid.
-packed closely together. -held in a fixed pattern. -vibrate about their fixed positions in the structure.
8 of 12
Explain particles in a liquid.
-almost tightly packed together as they are in solids. -held together by attraction forces, there is no fixed pattern -vibrating, but not in a fixed position.
9 of 12
Explain particles in a gas.
-very widely separated. -no fixed positions and the forces between them are very weak. continuous, rapid, random motion.
