Question

M=10г t1=960 градусов t2=60 градусов с=250дж кг *градусов цельсия найти q-?

Answer 1

СИ: m= 0,01 кг
$Q=c*m*(t2-t1)$= 250* 0, 01*(60-960)= - 2250 Дж

Answer 2

To solve this problem, we can use the formula:

q = M * c * ΔT

where q is the heat energy absorbed or released, M is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.

In this case, we are given:

M = 10 g (note that it's best to convert this to kilograms for consistency with the units of specific heat capacity) t1 = 960 degrees Celsius t2 = 60 degrees Celsius c = 250 J/kg°C

First, we need to calculate the change in temperature, ΔT:

ΔT = t2 - t1 = 60°C - 960°C = -900°C

Note that the change in temperature is negative because the temperature decreased from t1 to t2.

Now we can plug in the values to the formula:

q = (10 g) * (250 J/kg°C) * (-900°C) q = -2,250,000 J

Therefore, the heat energy released is -2,250,000 J (note that the negative sign indicates that the heat was released, not absorbed).
