Answer: A) it remains at a 100 B) 1130J
Explanation:
A) Water boils at a hundred after which further heat is used up to break bonds in order to allow water to boil rather than being used up to increase the temperature of the water that is boiling.
B) Energy/heat = specific latent heat x mass
E = 2260 x 0.5 (kg)
E = 1130 J
