Final Temperature = 70°C

Temperature change, ΔT = 70 - 23.5 = 46.5

Heat = ?

The parameters are related by the equation;

H = mc ΔT

where c = specific heat capacity = 4.18 J/g°C

H = 100 * 4.18 * 46.5 = 19437 J

Explanation:

The distance Earth orbits the Sun is just right for water to remain a liquid and for life to not be frozen or fried. This distance from the Sun is called the habitable zone, or the Goldilocks zone.
