Ans: Heat required = 1159.2 J or 1.16 kJ
Given:
Mass of iron, m = 100.0 g
Initial temp, T1 = 15.0 C
Final temp, T2 = 40.2 C
specific heat of iron, c = 0.46 J/gC
To determine:
Heat required, q
Explanation:
Heat required is given as:
q = mcΔT
[tex]q = 100.00 g * 0.46 J/gC * (40.2-15.0) C \\\\q = 1159.2 J[/tex]
