What is wrong with these diagrams of particle arrangement in solids, liquids and gases?

What should the correct models look like?

SolidLiquidGas

2Change of StateWhat are the different changes of state?Can you explain how these occur in terms of particles and energy?

Heating and Cooling CurvesHeating waxWhat are you going to measure?What time intervals are you going to record the temperature at?How could you display your results?Draw a graph of your heating curve.

Graph MarksHave you drawn a line graph?Does your graph have a correctly scaled x axis, including a label with units?Does your graph have a correctly scaled y axis, including a label with units?Are the points plotted correctly?Is there a straight line or a smooth curve of best fit?Does it have a title?

How does your graph compare to this typical heating graph?

Change Of State add labels to your graph to explain what is happeningTemperature (c)Time (s)http://www.kentchemistry.com/links/Matter/HeatingCurve.htm

Can you explain what is happening in these pictures?Why is the glass wet on the outside?

This cup contains ice. Why does it appear to have steam coming off it?

What have you learnt?Can you describe how particles are arranged in solids, liquids and gasses? Can you explain changes of state in terms of particles and energy?Can you draw and annotate a heating and cooling curve?
