прозрачное стекло не нагревается т.к. оно пропускает излучение.
закопченое их не пропускает и нагревается.
сила излучения у разных утюгов разная поэтоме температура тоже.
белый снег отражает солнечные лучи,а грязный черный принимает их и нагревается.
передается тепло светом и ультрафиолетовым излучением.
