Question

Стальной молоток нагретый до температуры 720 градусов будет охладили до 14 градусов при этом он передал окружающей среде количество теплоты равное 203 кДж Какова масса молотка?

Answer 1

Дано:
t1=720°C
t2=14°C
Q=203(кДж)=203000(Дж)
Найти :
m-?
Решение:
Q=c*m*Δt ;
m=Q/c*Δt;
c - удельная теплоемкость вещества , у стали 500
m - масса
Δt - разница температур
m=203000/500*(14-720)=203000/353000=0.575 кг =575 г
Ответ: 575г

Answer 2

Calculation of the mass of the hammer

To calculate the mass of the hammer, we can use the equation for heat transfer:

Q = mcΔT

Where: - Q is the amount of heat transferred (203 kJ) - m is the mass of the hammer (unknown) - c is the specific heat capacity of steel (unknown) - ΔT is the change in temperature (720°C - 14°C = 706°C)

To solve for the mass of the hammer, we need to find the specific heat capacity of steel. Unfortunately, the search results provided do not contain the specific heat capacity of steel. Therefore, we cannot provide a specific answer to the question at this time.
