Question

A 35.66g sample of copper is heated using 600j of energy. if the original temperature of the copper is 85C what is its final temperature?
Specific heat of copper: 0.38j/gC

A -6.39
B 6.39
C -78.61
D 91.4

Answer 1

This problem is providing the mass, energy, initial temperature and specific heat of a sample of copper that is required to calculate the final temperature.

Thus, we recall the general heat equation:

$Q=mC(T_f-T_i)$

Which has to be solved for the final temperature, $T_f$ as follows:

$T_f=T_i+\frac{Q}{mC}$

Finally, we plug in the numbers to obtain:

$T_f=85\°C+\frac{600J}{35.66g*0.38\frac{J}{g\°C} } \\\\T_f=129.3\°C$

However, this result is not given in the choices.
