An object with a mass of #10 g# is dropped into #240 mL# of water at #0^@C#. If the object cools by #120 ^@C# and the water warms by #8 ^@C#, what is the specific heat of the material that the object is made of?
Here,the heat energy liberated by the object will be taken up by the water as a result of which,both will come to a thermal equilibrium.
So,heat energy liberated by the object is
Now,heat energy absorbed by water is
So,equating both we get,
The specific heat is
The heat is transferred from the hot object to the cold water.
For the cold water,
For the object
The specific heat of water
The mass of the object is
The mass of the water is
