# An object with a mass of #8 g# is dropped into #50 mL# of water at #0^@C#. If the object cools by #5 ^@C# and the water warms by #70 ^@C#, what is the specific heat of the material that the object is made of?

Thespecific heat is

The heat is transferred from the hot object to the cold water.

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 #21 g# is dropped into #400 mL# of water at #0^@C#. If the object cools by #150 ^@C# and the water warms by #12 ^@C#, what is the specific heat of the material that the object is made of?
- An object with a mass of #60 g# is dropped into #700 mL# of water at #0^@C#. If the object cools by #40 ^@C# and the water warms by #16 ^@C#, what is the specific heat of the material that the object is made of?
- An object with a mass of #1 kg#, temperature of #160 ^oC#, and a specific heat of #9 J/(kg*K)# is dropped into a container with #27 L # of water at #0^oC #. Does the water evaporate? If not, by how much does the water's temperature change?
- An object with a mass of #110 g# is dropped into #750 mL# of water at #0^@C#. If the object cools by #70 ^@C# and the water warms by #5 ^@C#, what is the specific heat of the material that the object is made of?
- How does specific heat of metal compare to that of water?
