A single drop of water is made up of more than a billion trillion extremely tiny water molecules. 3 The particles in a substance are the same whether its in the solid, liquid or gas state, but their arrangement and movement change. There are over 100 elements. The particles in gases are widely spaced and randomly arranged, meaning they can be easily compressed or squashed. They therefore hit the surface with more force and a greater number of impacts per second. The goal is for students to begin thinking about water, or any substance, on the molecular level and to conclude that water molecules must be attracted to one another. Internal energy is the total kinetic energy and potential energy of all the particles in a system. Measure the mass of an empty beaker.
