Answer 2

Calculation of Heat Released

To calculate the amount of heat released when a mass of 4 tons of iron cools down by 35°C, we can use the formula:

Q = mcΔT

Where: - Q is the amount of heat released, - m is the mass of the substance (in this case, 4 tons), - c is the specific heat capacity of the substance (iron), - ΔT is the change in temperature (35°C).

To find the specific heat capacity of iron, we can refer to the search results.

According to the specific heat capacity of iron is approximately 0.45 J/g°C.

Now, let's calculate the amount of heat released:

Q = (m * c * ΔT)

Q = (4,000 kg * 0.45 J/g°C * 35°C)

Q = 6,300,000 J

Therefore, the amount of heat released when 4 tons of iron cools down by 35°C is approximately 6,300,000 joules (J).

Please note that the specific heat capacity value used in this calculation is an approximation.
