The state of the matter table Fill in the state of matter table that you were given. Identify main patterns in: Particle movement Size and shape Distance between particles or volume. Chocolate cake is made up of matter. You are made of matter. Properties describe matter. A block of wood, milk, and air all have properties.

Latent heat of fusion and vaporization Aim: To investigate the temperature change when wax solidifies. Experiment: In groups of 3 or 4. Grab one beaker of wax each, heat the wax until molten. And then insert a thermometer into the wax and take a reading every 30 seconds. Once the wax has set and solidified (and temperature not dropping further), remove the thermometer and return everything to where they belong. Then draw a graph using the data you collected and

Latent heat of fusion and vaporization Particles are attracted to each other and the attraction become smaller as particles get further apart. Latent heat of fusion is the heat required to weaken the attraction between particles so that a solid can turn into a liquid. Latent heat of vaporization is the heat required for liquid to turn into gas.
