The final temperature of the water is determined as 50.55 ⁰C.

<h3>Final temperature of the water</h3>

The final temperature of the water is determined from the following calculations;

Q = mcΔθ

Δθ = Q/mc

where;

  • Q is the amount of energy = 81 kcal = 338904 J
  • c is specific heat capacity of water = 4,200 J/kgC

Δθ = 338904 /(3.5 x 4200)

Δθ = 23.05 °C

Final temperature = T₁ + Δθ

Final temperature = 27.5°C + 23.05 °C = 50.55 ⁰C.
