                Design and Use of Thermometers (cont’d)

                Students should be able to:

                1.3.     discuss the advantages and  Give   typical   situations
                         disadvantages  of  these  where the different types of
                         thermometers; and,         thermometers  will  be  best

                                                    Use the equation
                                                      =     × 273.16
                                                          

                2.        Thermal Properties

                Students should be able to:

                2.1.     express the internal energy
                         of  a  system  as  the  sum  of
                         the  kinetic  and  potential
                         energies  associated  with
                         the  molecules  of  the
                         system;

                2.2.     relate a rise in temperature
                         to  an  increase  in  internal
                         energy;

                2.3.     explain  the  terms  ‘heat
                         capacity’ and ‘specific heat
                         capacity’;
