ответ:

объяснение:

q=30400 дж

t2=20 град.

m=200 г=0,2кг

с=380 дж/(кг*с) - удельная теплоемкость меди

t1=?

запишем формулу для теплоты

q=m*c*(t1-t2)

отсюда найдем искомую температуру

q / m*c = (t1-t2)

t1=q / (m*c) + t2   =30400 / (0.2*380)   +20 = 420 градусов

теперь вопрос в написано при охлаждении медного паяльника до 20 градусов но не написано в каких. если это по цельсию - то обжечься можно, но бытовые паяльники работают 280 - 350 градусов цельсия.

а вот если температура взята по кельвину ,

то в переводе получим 420 к   = 147 градусов по цельсию. ожог то же обеспечен.

вы уже знаете, что все вещества состоят из мельчайших частиц. люди догадывались об этом давно.только доказать это было трудно потому что частицы настолько маленькие, что их невозможно было увидеть.это значит,что прямого доказательство их существования не было. греческий греческий учёный демокрит считал что все вещества состоят из мельчайших частиц. о том,что все все тела состоят из мельчайших частиц позволяют судить по некоторым опытом.например попытаемся сжать теннисный мячик.при этом объем воздуха, который заполняет мяч, уменьшиться.еще объем тела изменяется при его охлаждении и нагревании. при нагревании объём тела увеличивается, а при охлаждении уменьшается.

молекула вещества — мельчайшая частица данного вещества.например, самая маленькая частица воды это молекула воды.даже небольшие тела состоят из огромного числа молекул. из-за малых размеров невидимые невооружённым глазом. специально для этого есть прибор который называется электронный микроскоп.на рисунке 21 показано расположение молекул белка.
