An object with a mass of #20 g# is dropped into #750 mL# of water at #0^@C#. If the object cools by #90 ^@C# and the water warms by #18 ^@C#, what is the specific heat of the material that the object is made of?
suppose,the specific heat of the object is
So,during this process of achieving thermal equilibrium,the heat energy released by the object was taken by the water.
So,we can write,
The specific heat is
The heat is transferred from the hot object to the cold water.
For the cold water,
For the hot object
The specific heat of water
The mass of the object is
The mass of the water is
