Answer :
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
