Final answer:

The specific heat of the metal is calculated using the formula for heat transfer (q = mcΔT). With 8250 J of heat absorbed, a mass of 5 kg, and a temperature change of 15 °C, the specific heat is found to be 110 J/kg°C.

Step-by-step explanation:

To calculate the specific heat of a metal when given the mass, the amount of heat absorbed, and the change in temperature, you can use the formula:

q = mcΔT

Where:

q is the heat absorbed (in Joules),

m is the mass of the substance (in kilograms),

c is the specific heat capacity (in J/kg°C),

ΔT is the change in temperature (in °C).

Rearranging the formula to solve for c gives:

c = q / (mΔT)

Given q = 8250 J, m = 5 kg, and ΔT = 15 °C, we can plug these values into the formula:

c = 8250 J / (5 kg * 15 °C) = 8250 J / (75 kg°C) = 110 J/kg°C

The specific heat of the metal is 110 J/kg°C.
