17. В цилиндре под поршнем находилось твёрдое вещество. Цилиндр поместили в печь. Сначала его нагревали, а в некоторый момент начали охлаждать. На рисунке 185 приведён график изменения температуры t вещества с течением времени τ. Дайте названия процессам, которым соответствуют участки графика.

Решение 4. №17 (с. 243)

Дано:

График зависимости температуры t вещества от времени τ. Изначально вещество находилось в твёрдом состоянии.

Найти:

Названия процессов, которым соответствуют участки графика.

Решение:

Проанализируем каждый участок графика.

Участок AB

На этом участке температура вещества растет со временем. Поскольку изначально вещество было в твёрдом состоянии, здесь происходит процесс нагревания твёрдого вещества.

Ответ: Нагревание твёрдого вещества.

Участок BC

Температура вещества остается постоянной, что указывает на фазовый переход. Происходит плавление — переход вещества из твёрдого состояния в жидкое. Вся подводимая энергия идёт на разрушение кристаллической решётки.

Ответ: Плавление.

Участок CD

После полного расплавления вещество находится в жидком состоянии. На этом участке температура жидкости растёт, что соответствует процессу нагревания жидкости.

Ответ: Нагревание жидкости.

Участок DE

Температура вещества снова остаётся постоянной. Это свидетельствует о следующем фазовом переходе — кипении (интенсивном парообразовании). Жидкость превращается в газ (пар).

Ответ: Кипение (парообразование).

Участок EF

Вся жидкость превратилась в пар. На этом участке происходит нагревание газа (пара).

Ответ: Нагревание газа.

Участок FG

В точке F процесс нагревания прекращается и начинается процесс охлаждения. На участке FG температура газа (пара) понижается. Это процесс охлаждения газа.

Ответ: Охлаждение газа.

Участок GH

Температура вещества остается постоянной при охлаждении. Это обратный фазовый переход — конденсация. Газ (пар) превращается в жидкость. Температура конденсации равна температуре кипения.

Ответ: Конденсация.

Участок HK

Весь пар сконденсировался в жидкость. На этом участке происходит охлаждение жидкости.

Ответ: Охлаждение жидкости.

Участок KL

Температура вещества снова становится постоянной. Происходит следующий обратный фазовый переход — кристаллизация (отвердевание). Жидкость превращается в твёрдое тело. Температура кристаллизации равна температуре плавления.

Ответ: Кристаллизация (отвердевание).

Участок LM

Вся жидкость затвердела. На этом участке происходит охлаждение твёрдого вещества.

Ответ: Охлаждение твёрдого вещества.
