How much energy is needed to change 100 g of 0o c ice to 0o c water? the latent heat of fusion for water l=335,000 j/kg. hint: the heat (q) used to change from one phase to another phase of the matter is q=ml, where l is the latent heat. its unit is j/kg.

33.5 kJ

Explanation:

here there is no difference is made in the temperature. Only thing happens here is the conversion of the ice in to water of 0 degree. The heat energy taken from the outside is spent for this conversion.

we have ice 100g =0.1 kg

Appplying Q=mL

                  Q=

                   Q = 33 500 J

                   Q = 33.5 kJ

i think the answer is a and b

i wish you luck
