           Iron is a thermal              the hotness of electric
           conductor that                 iron.
           transfers the heat
           of electric iron to
           cloth for ironing
           it.

                                Heat is an essential component of
                                             life on earth.

                                Heat flows from hotter objects to
                                           cooler objects.

                                Heat cannot be lost but it is only
                                            transferred.

➢ Thermal equilibrium:

      Heat transfer from hotter object to cooler object until reach the
     same temperature.
