The heat energy transferred by the iron nail is 4680 J
Explanation:
The thermal energy transferred by a substance to another substance is given by the equation
[tex]Q=mC\Delta T[/tex]
where
m is the mass of the substance
C is its specific heat capacity
[tex]\Delta T[/tex] is its change in temperature
For the iron nail in this problem, we have:
m = 16 g
[tex]C=0.450 J/g^{\circ}C[/tex]
[tex]\Delta T = -650^{\circ}C[/tex]
So, the amount of heat energy given off by the nail is
[tex]Q=(16)(0.450)(-650)=-4680 J[/tex]
where the negative sign indicates that the heat is given off.
