An unknown substance has a mass of 11.9 g . when the substance absorbs 1.071×102 j of heat, the temperature of the substance is raised from 25.0 ∘c to 45.0 ∘c . what is the most likely identity of the substance?

The most likely identity of the substance is iron.

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed= Joules

m= mass of substance = 11.9 g

c = specific heat capacity = ?

Initial temperature of the water = = 25.0°C

Final temperature of the water =  = 45.0°CChange in temperature ,

Putting in the values, we get:

The specific heat of 0.45 is for iron and thus the substance is iron.
