The amount of energy required to melt a 10.7 g piece of ice at 0°C is:
( Q = m \times \text{heat of fusion} )
( Q = 10.7 , \text{g} \times 333 , \text{J/g} )
( Q = 3563.1 , \text{J} )

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
