№4 (с. 5)
Условие. №4 (с. 5)
скриншот условия
4. Расположите значения температуры в каждом случае в порядке убывания:
a) $283 \text{ K}$, $20 ^\circ \text{C}$;
б) $47 ^\circ \text{C}$, $390 \text{ K}$;
в) $-10 ^\circ \text{C}$, $10 \text{ K}$.
Решение. №4 (с. 5)
а) Дано:
$T_1 = 283 \text{ К}$
$t_2 = 20 \text{ °С}$
Найти:
Расположить значения температур в порядке убывания.
Решение:
Для сравнения значений температуры, выраженных в разных шкалах, необходимо привести их к одной единице измерения. Переведем температуру из градусов Цельсия (°C) в Кельвины (К), которые являются основной единицей температуры в системе СИ, по формуле $T = t + 273$.
Переведем температуру $t_2$ в Кельвины:
$T_2 = 20 + 273 = 293 \text{ К}$
Теперь сравним два значения: $T_1 = 283 \text{ К}$ и $T_2 = 293 \text{ К}$.
Поскольку $293 > 283$, то $T_2 > T_1$. В исходных единицах это означает, что $20 \text{ °С} > 283 \text{ К}$.
Располагая значения в порядке убывания, получаем: $20 \text{ °С}$, $283 \text{ К}$.
Ответ: $20 \text{ °С}$, $283 \text{ К}$.
б) Дано:
$t_1 = 47 \text{ °С}$
$T_2 = 390 \text{ К}$
Найти:
Расположить значения температур в порядке убывания.
Решение:
Переведем температуру $t_1$ из градусов Цельсия в Кельвины:
$T_1 = 47 + 273 = 320 \text{ К}$
Теперь сравним два значения: $T_1 = 320 \text{ К}$ и $T_2 = 390 \text{ К}$.
Поскольку $390 > 320$, то $T_2 > T_1$. В исходных единицах это означает, что $390 \text{ К} > 47 \text{ °С}$.
Располагая значения в порядке убывания, получаем: $390 \text{ К}$, $47 \text{ °С}$.
Ответ: $390 \text{ К}$, $47 \text{ °С}$.
в) Дано:
$t_1 = -10 \text{ °С}$
$T_2 = 10 \text{ К}$
Найти:
Расположить значения температур в порядке убывания.
Решение:
Переведем температуру $t_1$ из градусов Цельсия в Кельвины:
$T_1 = -10 + 273 = 263 \text{ К}$
Теперь сравним два значения: $T_1 = 263 \text{ К}$ и $T_2 = 10 \text{ К}$.
Поскольку $263 > 10$, то $T_1 > T_2$. В исходных единицах это означает, что $-10 \text{ °С} > 10 \text{ К}$.
Располагая значения в порядке убывания, получаем: $-10 \text{ °С}$, $10 \text{ К}$.
Ответ: $-10 \text{ °С}$, $10 \text{ К}$.
