Answer:
4235.7J or 4.2KJ
Explanation:
The heat required to raise the temperature of water is given by
H= mcθ
Where
H= heat required= ?????
m= mass of the water body=65.8 grams
c= heat capacity of the water= 4.18 J/g·ºC
θ=temperature change= 46.9°C- 31.5°C= 15.4°C
H= 65.8 ×4.18 × 15.4= 4235.7J or 4.2KJ
