Answer:
16.7 kJ
Explanation:
mass of water = 50 grams
change in temperature of water = 50⁰c
specific heat of fusion of water = 334 J/g
calculate the amount of heat needed/required
= mass of water * specific heat of fusion of water
= 50 grams * 334 J / g
= 16700 J
note : we use the specific heat of fusion of water because the temperature change given and the change is below 100⁰c hence the water is still in liquid form
