An object with a mass of #150 g# is dropped into #500 mL# of water at #0^@C#. If the object cools by #72 ^@C# and the water warms by #3 ^@C#, what is the specific heat of the material that the object is made of?

Probably Scandium (Sc) at
Explanation:
For water:
What we know-
#c=4.184J/g°C# #m=500g# #∆T=3°C#
For object:
What we know-
#m=150g# #∆T=-72°C# (The object cools)
Since heat gained
So,
Which is a little over the the specific heat of Scandium (Sc) which is
But as we have made a lot of assumptions over here, the material is probably Scandium.
