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.

- Sara has a fire in the fireplace to warm her 20°C apartment. She realizes that she has left the iron poker in the fire. How hot is the fire if the 0.60 m poker lengthens 0.30 cm? (αiron = 12 x 10-6°C-1)
- An object with a mass of #50 g# is dropped into #160 mL# of water at #0^@C#. If the object cools by #40 ^@C# and the water warms by #8 ^@C#, what is the specific heat of the material that the object is made of?
- An object with a mass of #4 kg#, temperature of #105 ^oC#, and a specific heat of #2 J/(kg*K)# is dropped into a container with #16 L # of water at #0^oC #. Does the water evaporate? If not, by how much does the water's temperature change?
- Some very hot rocks have a temperature of #220 ^o C# and a specific heat of #200 J/(Kg*K)#. The rocks are bathed in #40 L# of boiling water. If the heat of the rocks completely vaporizes the water, what is the minimum combined mass of the rocks?
- Some very hot rocks have a temperature of #250 ^o C# and a specific heat of #80 J/(Kg*K)#. The rocks are bathed in #250 L# of boiling water. If the heat of the rocks completely vaporizes the water, what is the minimum combined mass of the rocks?
