3. Вид теплопередачі - випромінювання. Опишіть та наведіть приклади.
4. Задача.
Деталі з латуні передали 100 кДж теплоти, після чого її температура зросла
на 50 °С. Яка маса деталі?
5. Задача.
В мідному тазу масою 4 кг нагрівають 10 літрів води.
Яку кількість теплоти потрібно витратити на нагрівання води та таза, якщо їх
початкова температура 20 °С, а кінцева 70 °С?

Відповідь:

1/ За нуль за шкалою Цельсія прийнята температура плавлення льоду (та замерзання води), а за 100 градусів — температура кипіння води (та конденсації пари) за нормального атмосферному тиску. Початково Цельсій за 100 градусів взяв температуру танення льоду, а за 0 — температуру кипіння води.
