The specific heat of the given sample of metal is 14.32 J/kg.K.

<h3>What is the Specific heat of a sample?</h3>

The specific heat of a sample is the amount of heat needed or required to raise the temperature of that sample by 1K. It is given by the formula:

Q = mCΔT

where;

  • Q = Heat transferred
  • m = Mass of the substance
  • C = Specific heat
  • ΔT= Change in temperature.

Recall that:

weight of a substance = mass × gravity

  • mass = 28.4 N/ 9.8 m/s²
  • mass = 3 N/m/s² = 3 kg

From the equation:

Q = mCΔT

\mathbf{C = \dfrac{1.25 \times 10^4 \ J}{3 \ Kg \times 291  \ K }}}

C = 14.32 J/kg.K
