✓When your hand touches the hot cup of tea, you feel hotness
   of the cup.

➢ What happens to an object when heat is transferred?
Heat transfer from hotter object to the cooler one then the

   molecules in cooler object moves faster while the hotter one moves
   slower.

Object with                    heat transfer            Object with
     high                                                    low

                               Materials divided into
                                            :

Thermal conductors                                      Thermal insulators

They are materials that allow                           They are materials that don’t
 thermal energy to transfer                              allow (resist) thermal energy
 through or allow heat to                                to transfer through or slow
 travel freely through them.                             down the heat transfer.

Example: Metals as iron.                                Example: Plastic, wood and
                                                         glass.
