Question

По куску кирпича и по куску меди, массы которых равны, ударили молотком с одной и той же силой одинаковое количество раз. Определи и обоснуй, какой кусок меньше нагреется. Удельная теплоёмкость кирпича равна 750 Дж/(кг·°C), удельная теплоёмкость меди равна 380 Дж/(кг·°C). Выбери и отметь правильный ответ.

Answer 1

Ответ:2

Объяснение:

Ошибка в данных: удельная теплоемкость стали 460

dt1=Q/c1*m=Q/460*m

dt2=Q/c2*m=Q/380*m

dt2>dt1

Но это пример, у вас вроде бы немного по другому!

Answer 2

The question at hand

The question asks us to determine and justify which piece, a brick or a piece of copper, will heat up less when struck with the same force an equal number of times. The specific heat capacities of the brick and copper are given as 750 J/(kg·°C) and 380 J/(kg·°C), respectively.

Understanding the problem

To solve this problem, we need to consider the concept of specific heat capacity. Specific heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. It is measured in J/(kg·°C). The higher the specific heat capacity, the more heat energy is required to raise the temperature of the substance.

Analysis and solution

To determine which piece will heat up less, we need to compare the specific heat capacities of the brick and copper. The piece with the higher specific heat capacity will require more heat energy to raise its temperature by the same amount.

Given that the specific heat capacity of the brick is
