A 90.0 g sample of an unknown metal absorbed 25.6 J of heat as its temperature increased 1.18 degrees C. What is the specific heat of the metal

Answer :

The specific heat of the metal is 241.05 J/kg°C

What is specific heat capacity?

Specific heat capacity can be defined as the amount of heat required to raise a unit mass of metal through 1 °C

To calculate the specific heat capacity of the metal, we use the formula below.

Formula:

  • Q = cm(t'-t)............... Equation 1

Where:

  • Q = Heat absorbed by the metal
  • c = specific heat capacity of the metal
  • m = mass of the metal
  • Δt = increase in temperature

make c the subject of the equation

  • c = Q/m(Δt)................. Equation 2

From the question,

Given:

  • Q = 25.6 J
  • m = 90 g = 0.09 kg
  • Δt = 1.18 °C

Substitute these values into equation 2

  • c = 25.6/(1.18×0.09)
  • c = 241.05 J/kg°C

Hence, the specific heat capacity of the metal is 241.05 J/kg°C.
