Answer:
= 3,702.816 Joules
Explanation:
Heat absorbed by water is equivalent to heat released by copper.
Heat absorbed is given by:
Q = mcΔT
where m is the mass, c is the specific capacity and ΔT is the change in temperature.
Mass = 1248 g
ΔT = 45°C - 22°C = 23°C
c = 0.129j/g°c
Heat = 1248 g × 23°C × 0.129j/g°C
= 3,702.816 Joules
