Answer:
8778 J
Explanation:
We'll begin by calculating the change in the temperature of water. This can be obtained as follow:
Initial temperature (T₁) = 10 °C
Final temperature (T₂) = 85 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 85 – 10
ΔT = 75 °C
Finally, we shall determine the heat required to raise the temperature of the water. This can be obtained as illustrated below:
Mass (M) = 28 g
Change in temperature (ΔT) = 75 °C
Specific heat capacity (C) = 4.18 J/gºC
Heat (Q) required =?
Q = MCΔT
Q = 28 × 4.18 × 75
Q = 8778 J
Thus, the heat required to raise the temperature of the water is 8778 J
