Решение 4. №4 (с. 78)
Процесс высыхания белья – это испарение воды с его поверхности. Скорость испарения напрямую зависит от нескольких ключевых факторов: температуры воздуха, скорости ветра и относительной влажности окружающего воздуха.
Относительная влажность показывает, насколько воздух насыщен водяным паром по сравнению с максимально возможным количеством при данной температуре. Чем выше относительная влажность, тем медленнее происходит испарение, так как воздуху сложнее "принять" в себя дополнительные молекулы воды.
На берегу моря происходит постоянное и интенсивное испарение воды с огромной водной поверхности. Из-за этого воздух в прибрежной зоне всегда имеет высокую относительную влажность, он насыщен водяными парами.
Вдали от моря, в континентальной части суши, источник постоянного испарения отсутствует, поэтому воздух там, как правило, значительно суше, то есть его относительная влажность ниже.
Таким образом, когда мокрое бельё висит на берегу моря, вода с него испаряется в уже сильно увлажненный воздух, и этот процесс идёт медленно. В то же время, вдали от моря, где воздух суше, он может поглотить гораздо больше влаги, что приводит к быстрому высыханию белья.
Ответ: На берегу моря воздух имеет высокую влажность из-за постоянного испарения воды с поверхности моря. Высокая влажность воздуха замедляет процесс испарения воды с поверхности белья, поэтому оно сохнет дольше, чем вдали от моря, где воздух обычно суше.
