3960 J of heat are added to a 27.6 g sample

Question

of iron at 25
◦
C. What is the final temperature of the iron? The specific heat of iron is
0.449 J/g · K.
Answer in units of K

Answer 1

1)Convert 25* Celsius to Kelvin.
Celsius + 273.15 = Kelvin

Plug the given numbers in this formula and solve for final temperature.
q = mcΔT

where
q = heat energy
m = mass
c = specific heat
ΔT = change in temperature = final temperature - initial temperature
