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.
