Answer:
=384.48°C
Explanation:
Change in enthalpy is negative because heat energy is lost to the surroundings.
Change in enthalpy= mass ×specific heat capacity× Change in temperature.
ΔH=MC∅
m=14grams
C of iron= 0.45 J/g°C
∅=?
186.0J= 14.0g × 0.45J/g°C×∅
186=6.3∅
∅=29.5°C
Final temperature= 414.0°C - 29.52°C
=384.48°C
