: How much energy is required to heat an iron nail with a mass of 25.5 grams from 65°C until it becomes red hot at 720°C?

Evgen [1.6K]

Q = mct

-Q= energy in Joules

-m = mass in grams

-c= specific heat capacity in J/g degree C

-t = delta temperature in degrees Celsius

So,

Q = m c t

Q = (7 grams)(0.448J/g C)(750 C - 25 C)

Q = 2273.6 J

Your final answer = 2273.6 Joules
