Question

1) How much energy would be required to melt 15.0 g of ice at 0°C?

= 334 J/g)


(AH fusion

Answer 1

5010J

Step-by-step explanation:

The following data were obtained from the question:

Mass (m) = 15g

Heat of fusion (ΔHf) = 334J/g

Heat required (Q) =..?

The heat energy required to melt the ice can be obtained as follow:

Q = m·ΔHf

Q = 15 x 334

Q = 5010J

Therefore, the heat energy required to melt the ice is 5010J.
