Give descriptions to show understanding of the following. There will be a test on Monday.
(a) describe solids, liquids and gases in terms of the spacing, ordering and motion of atoms or molecules;
(b) describe a simple kinetic model for solids, liquids and gases;
(c) describe an experiment that demonstrates Brownian motion and discuss the evidence for the movement of molecules provided by such an experiment;
(d) define the term pressure and use the kinetic model to explain the pressure exerted by gases;
(e) define internal energy;
(f) explain the difference between heat and temperature;
(g) explain why temperature does not change during a change of state;
(h) describe using a simple kinetic model for matter the terms melting, boiling and evaporation.
