How much heat is needed to melt 500g steel at the melting temperature?
| June 24, 2021 | education
The amount of energy required to melt steel is calculated using the formula:
Q = λ * m, where λ is the specific heat of melting of steel (λ = 84 kJ / kg = 84 * 10³ J / kg), m is the mass of steel (m = 500 g = 0.5 kg).
Let’s calculate the required amount of energy to melt steel:
Q = λ * m = 840 * 10³ * 0.5 = 420 * 10³ J = 420 kJ.
Answer: To melt steel, you need to spend 420 kJ of heat.
