A 6.50-g sample of copper metal at 25.0 °C is heated by the addition of 84.0 J of energy. The final temperature of the copper is __________°C. The specific heat capacity of copper is 0.38 J/g-K.

Question

Quizplus · Accepted Answer

We can use the formula:

q = m*c*ΔT

where q is the energy added, m is the mass of the copper, c is its specific heat capacity, and ΔT is the change in temperature.

Rearranging the formula, we get:

ΔT = q / (m*c)

Substituting the given values, we have:

ΔT = 84.0 J / (6.50 g * 0.38 J/g-K)

ΔT = 34.0 K

Finally, the final temperature is:

T_final = T_initial + ΔT

T_final = 25.0°C + 34.0K = 59.0°C

Therefore, the answer is D) 59.0.
