Answer 2

Calculation of the Mass of the Metal Detail

To calculate the mass of the metal detail, we can use the formula:

Q = mcΔT

Where: - Q = heat energy absorbed (in joules) - m = mass of the metal detail (in kilograms) - c = specific heat capacity of the metal (in joules per kilogram per degree Celsius) - ΔT = change in temperature (in degrees Celsius)

Given: - Q = 500 kJ = 500,000 J - ΔT = 50°C - Specific heat capacity (c) is not provided in the search results, so we'll use the average specific heat capacity for metals, which is approximately 500 J/kg°C.

Using the formula, we can solve for the mass (m):

m = Q / (cΔT)

Substituting the given values: m = 500,000 J / (500 J/kg°C * 50°C)

Calculating: m ≈ 20 kg

So, the mass of the metal detail is approximately 20 kilograms.
