The heat absorbed by the metal is 729.9 kJ.

We can calculate the heat absorbed by the copper using the formula below

⇒ Formula:

Q = cm(t₂-t₁)............... Equation 1

⇒ where:

  • Q = Heat absorbed by the copper
  • c = Specific heat capacity of the copper
  • m = Mass of the copper
  • t₁ = Initial temperature
  • t₂ = Final Temperature

From the question,

⇒Given:

  • m = 6.22 kg
  • c of copper = 385 J/kg.°C
  • t₁ = 20.5°C
  • t₂ = 325.3°C

⇒Substitute these values into equation 1

  • Q = 6.22×385(325.3-20.5)
  • Q = 6.22×385×304.8
  • Q = 729904.56 J
  • Q = 729.9 kJ

Hence the heat absorbed by the metal is 729.9 kJ
