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.

- An object with a mass of #120 g# is dropped into #800 mL# of water at #0^@C#. If the object cools by #24 ^@C# and the water warms by #3 ^@C#, what is the specific heat of the material that the object is made of?
- Some very hot rocks have a temperature of #420 ^o C# and a specific heat of #270 J/(Kg*K)#. The rocks are bathed in #35 L# of boiling water. If the heat of the rocks completely vaporizes the water, what is the minimum combined mass of the rocks?
- An object with a mass of #12 g# is dropped into #240 mL# of water at #0^@C#. If the object cools by #120 ^@C# and the water warms by #6 ^@C#, what is the specific heat of the material that the object is made of?
- What happens when an object at a high temperature touches an object at lower temperature?
- An object with a mass of #64 g# is dropped into #210 mL# of water at #0^@C#. If the object cools by #96 ^@C# and the water warms by #7 ^@C#, what is the specific heat of the material that the object is made of?
