An aluminium block has a mass of 1.5 kg.
The block is heated using an electrical heater until it reaches a final temperature of 95 ∘C95\text{ }^\circ\text{C}95 ∘C.
The specific heat capacity of aluminium is 900 J/kg ∘C900\text{ J/kg }^\circ\text{C}900 J/kg ∘C.
The total amount of thermal energy transferred to the aluminium block is 101 250 J101\,250\text{ J}101250 J.
Calculate the temperature of the aluminium block before it was heated.
