Answer:
The right answer is option 3.
Explanation:
The minimum amount of heat required to melt ice is:
![Q=m_{ice}\cdot L_{f}](https://tex.z-dn.net/?f=Q%3Dm_%7Bice%7D%5Ccdot%20L_%7Bf%7D)
Where
and
is the latent heat of fussion, measured in kg and kJ/kg, respectively.
![Q = (0.02\,kg)\cdot (334\,\frac{kJ}{kg} )](https://tex.z-dn.net/?f=Q%20%3D%20%280.02%5C%2Ckg%29%5Ccdot%20%28334%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D%20%29)
![Q = 6.68\,kJ\,(6680\,J)](https://tex.z-dn.net/?f=Q%20%3D%206.68%5C%2CkJ%5C%2C%286680%5C%2CJ%29)
The right answer is option 3.
