Question 1

A 0.10 kg aluminium component is initially at 20 ∘C20\ ^\circ\text{C}20 ∘C. It is heated until it has just melted completely. The melting point of aluminium is 660 ∘C660\ ^\circ\text{C}660 ∘C. The specific heat capacity of solid aluminium is 900 J/kg ∘C900\ \text{J/kg}\, ^\circ\text{C}900 J/kg∘C and its specific latent heat of fusion is 397 000 J/kg397\,000\ \text{J/kg}397000 J/kg.

Calculate the total thermal energy needed to heat and melt the aluminium component.
