Answer:
33300J
Explanation:
Given parameters:
Mass of ice = 100g = 0.1kg
Initial Temperature of water = 0°C
Final temperature = 0°C
Unknown:
Amount of energy = ?
Solution:
The amount of energy is given by;
Amount of energy = mL
m is the mass
L is the latent heat of fusion = 3.33 x 10⁵ J/kg
Amount of energy = 0.1kg x 3.33 x 10⁵J/kg
Amount of energy = 33300J
