The specific heat for iron is 0.459J/g^0C

Explanation:

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

$Q=m\times c\times \Delta T$

Q = Heat absorbed= 1050 Joules

m= mass of substance = 220.0 g

c = specific heat capacity = ?

Initial temperature = T_i = 10.0°C

Final temperature = T_f = 20.4°C

Change in temperature , $\Delta T=T_f-T_i=(20.4-10.0)^0C=10.4^0C$

Putting in the values, we get:

$1050=220.0\times c\times 10.4^0C$

c=0.459J/g^0C

The specific heat for iron is 0.459J/g^0C
