Answer:
15.00000652 °C
Explanation:
From the question,
Q = cm(tâ-tâ)................ Equation 1
Where Q = heat gained by the liquid, c = specific heat capacity of the liquid, m = mass of the liquid, tâ = Initial Temperature of the liquid, tâ = Final temperature of the liquid.
Given: Q = 3.33 J, c = 511 J/kg°C, m = 1000 kg, tâ = 15°C
Substitute these values into equation 1 and solve for tâ
3.33 = 511Ă1000(tâ-15)
3.33 = 511000(tâ-15)
(tâ-15) = 3.33/511000
(tâ-15) = 0.0000065
tâ = 15+ 0.0000065
tâ = 15.00000652 °C
