Answer:

39270 J

Step-by-step explanation:

The quantity of heat required to raise the temperature of a substance from its initial temperature to its final temperature is given by:

Q = mCΔT

m = mass of substance, C = specific heat capacity of substance, ΔT = temperature change = final temperature - initial temperature

Melting point = 0°C, boiling point = 100°C, m = 93.5 g = 0.0935 g, ΔT = boiling point - melting point = 100 - 0 = 100°C, C = 4200 J/kg°C

Q = mCΔT

Q = 0.0935 × 4200 × 100 = 39270 J
